        <p>This paper examines Jewish dietary laws (kashruth) as a knowledge domain, focusing on the ways tacit knowledge has impacted the development and continued use of this dietary ontology. Building from this case study, a framework is proposed for categorizing tacit expressions and assessing their impact on knowledge organization practices.

      <title>1. Introduction</title>
      <p>With the incremental Hellenization of the Southern Levant bringing significant changes to the
cultural landscape of ancient Palestine, to be a Jew in the second century BCE was to seemingly exist
in both internal and external conflict. As few personal accounts have survived from the Second Temple
period (516 BCE - 70 CE), the more affective aspects of this narrative admittedly demand a potentially
anachronistic kind of empathy, but David Kraemer nonetheless asks his readers to situate the formation
and initial acceptance of today’s Jewish dietary laws (kashruth) within this tableau, arguing:
This was the period when, after centuries of formation and
accretion, the Torah, along with the historical and classical
prophets, had achieved their canonical formation. This was the
period when these books were accepted as authoritative by the
majority of Jews. This was the period when the laws they
describe defined the life of Jewry, individually and as a nation.</p>
      <p>[1]
Before we can understand Jewish dietary practices in their contemporary form, we must first understand
the social domain in which they were first developed and refined. Mirroring Kraemer’s core
methodological positionality, Hjørland emphasizes that historical research methods provide valuable
tools for domain assessment. “When it comes to understanding documents, organisations, systems,
knowledge and information,” he argues, “a historical perspective and historical methods are often able
to provide a much deeper and more coherent and ecological perspective compared to non-historical
kinds of research of a mechanist nature” [2].</p>
      <p>Like all things, knowledge communities change and adapt to external and internal influences, and
the ancient Jews were no different. Following centuries of development and debate, the Written Torah
reached its canonical form in roughly 200 BCE, give or take a hundred years. Yet even without broader
community recognition of the now-central text, the historical record shows that a distinctly Jewish
identity had persisted for generations prior, suggesting that a similarly distinct way of eating also
precedes the formal documentation of the dietary laws. So although it was at this time, and within this
social climate, that Judean religious leaders “sought to create a bulwark against incursions on Jewish
identity” [1] by forming dietary categories separating Jews from gentiles, they did so using an inherited
collection of values, knowledges, and beliefs modified to meet the present moment. Historical
knowledge reduced to lists of dates and events fails to document this epistemological lineage operating
on a somatic, tacit level.</p>
      <p>The primary goal of this paper is to present a domain-analytic approach for identifying and
understanding the influence of tacit knowledge on knowledge organization (KO) practices. This
proposed framework suggests we can identify “traces” of tacit knowledge in documented language
using two communicative characteristics: verbal omission and self-disclosure. Based on these two
qualitative metrics, I have identified three general types of tacit manifestations: 1) tacit knowledge
directly identified through self-disclosure, 2) tacit knowledge indirectly identified through
selfdisclosure, and 3) tacit knowledge indirectly expressed through verbal omission. The kashruth case
study at the end of this paper seeks to illustrate the characteristics of this third tacit type, an application
of the proposed methodology, and the project’s implications for future KO research.

      <title>Notes on terminology</title>
      <p>In this paper, “verbal communication” is interpreted broadly and describes any form of
communication expressed using words, which includes spoken, written, and signed language.
Communication facilitated by any other means - namely gesture, facial expression, and body language
- will be referred to as “non‐verbal communication” [3]. Ostensive definition, or what Polanyi refers to
as “naming-cum-pointing” [4], is a common example of gestural non-verbal communication.</p>
      <p>The process of articulating something using verbal communication will be referred to as
“explication.” Here, “explicit knowledge” and “explicable knowledge” both describe types of
knowledge that can be sufficiently explicated. Any concept, idea, thing, or action that can be internally
or instinctively understood by an individual yet cannot be articulated verbally is a form of “tacit
knowledge.”</p>
    </sec>
    <sec id="sec-3">
      <title>2. Methodology</title>
      <p>KO researchers who analyze historical domains must excavate organizational tendencies, norms,
and values from the remnants of the past. Discourse analysis works fairly well on recorded forms of
explicable knowledge, yet their tacit counterparts cannot be captured in equally direct ways and,
inevitably, evade detection under these document-centric research protocols.</p>
      <p>To indirectly identify tacit influences through verbalized language, I build upon influential
scholarship on “archival silence” [5] to propose a unique domain-analytic approach [6] that “interpret[s]
the use of tools, of probes, and of pointers” [4] that suggest the application of embodied knowledge.</p>
    </sec>
    <sec id="sec-4">
      <title>3. Documenting domain-specific tacit knowledge</title>
      <p>Polanyi succinctly summarized tacit knowledge as our ability to “know more than we can tell,”
explaining, “Because our body is involved in the perception of objects, it participates thereby in our
knowing of all other things.” This embodiment can provide us with an intuitive understanding of
something without supplying the means to verbally communicate what it is that we actually know. His
classic examples are bike riding and swimming, two common activities that, once learned, are easily
performed using muscle memory. Verbal instructions of either, however, are less straightforward. “I
both know how to carry out these performances as a whole and also know how to carry out the
elementary acts which constitute them, though I cannot tell what these acts are.” [4]</p>
      <p>Within KO practices, this gap between what one “knows” and can “tell” is often circumvented by
focusing on the material objects that “convert” tacit knowledge into “explicit, objective, or public”
expressions [7]. Burnett and Lloyd discuss a similarly transformative process in their discussion of
“hidden knowledge,” claiming that the tacit-to-explicit conversion renders the hidden discoverable [8].
For immersive and experiential work genres, such as dance, music, and performance art, discoverability
within a KOS is often contingent upon a cataloger’s ability to flatten temporal and spatial attributes into
more static terminology, a tradeoff that affords user access at the potential expense of particular
arguably essential - qualities. Littletree, Belarde-Lewis, and Duarte explain that many tangible and
intangible expressions of Indigenous knowledge are ontologically centered in a relationality counter to
industry-standard KO concepts [9]. These relationships, assemblages, and entanglements are equal in
importance to other more observable qualities, but a one-to-one conversion from tacit to explicit will
often fail to capture this embodied knowledge.</p>
      <p>Still, there are situations where tacit knowledge simply needs to be shared in one way or another.
Within many professional domains, colleagues develop practical methods for exchanging complex and
tacit information, a phenomenon well studied by knowledge management researchers [10, 11, 12, 13].
Cognitive Work Analysis (CWA) mirrors the underlying goals of this KM work and has found valuable
usage within KO proper [e.g. 14, 15, 16, 17]. As a supplement to traditional domain analysis, CWA
uses ethnographic methods to “gain entry to the symbolic cultural knowledge of the actors in a domain”
[15], which can reveal the values, interactions, and norms of a domain that cannot be formally
documented or described. While certain practices can only be fully understood by actors within a
specific knowledge community, CWA provides means for identifying and acknowledging these
essential attributes. This paper seeks to contribute to and expand upon this literature by addressing tacit
knowledge and its powerful influence on our KO practices.</p>

      <title>4. Documenting domain-specific tacit knowledge</title>
      <p>As an embodied phenomenon, tacit knowledge cannot be communicated using straightforward
verbal approaches. Instead, it must be identified through the “tools, of probes, and of pointers” noted
by Polanyi, which I associate with two specific discursive features: verbal omission and self-disclosure.
Depending on the case at hand, one or both qualities may be relevant. Based on their amenability to
each characteristic, expressions of tacit knowledge can be sorted into one of the three categories
summarized in Table 1.
4.1.</p>
    </sec>
    <sec id="sec-6">
      <title>Verbal omission</title>
      <p>As noted previously, tacit knowledge is often suggested through silence. If most relevant,
domainspecific factors have already been explicitly incorporated into a KOS, we can develop a situated and
contextual understanding of a knowledge base to determine what things are missing. Since this is a
fundamentally speculative process, we must consider - and, whenever possible, control for - any
alternative motivations for knowledge omission.</p>
    </sec>
    <sec id="sec-7">
      <title>4.2. Self-Disclosure</title>
      <p>Although tacit knowledge cannot be verbally articulated, one can still be aware of and acknowledge
its influence. This kind of analytical reflection is rarely incorporated into the KO system itself, but
supportive and adjacent documentation can provide an opportunity for self-disclosure.</p>
      <p>Generally speaking, this type of direct admission removes most of the guesswork and is a more
conclusive “trace” than verbal omissions. Of course, there is one inevitable concern: people sometimes
lie. While tacit knowledge can prevent someone from verbalizing or recognizing what it is they know,
we must consider the fact that there are political, cultural, and social circumstances in which feigning a
tacit limitation is preferential to coming clean about one’s intentional or accidental exclusion of
explicable knowledge. Within a KO context, unrelated factors, such as the accidental deletion or loss
of collected information, must also be considered.</p>

      <title>5. Distinguishing between Types 1 and 2: direct vs. indirect expressions</title>
      <p>Type 1 is by far the easiest form of tacit knowledge to identify - it is also the least common of the
three. The expression of Type 1 tacit knowledge necessitates an awareness in the speaker that requires
pre-exposure in one of two forms: 1) psychological priming, in which the subject passively acquires an
“internal readiness” [18] to recognize tacit knowledge, or 2) pre-training where the subject is actively
taught to identify tacit knowledge. An excellent example of this is the U.S. Supreme Court case
Jacobellis v. Ohio (1964), in which Justice Potter Stewart famously rejected calls to define “obscenity,”
instead writing, “I shall not today attempt further to define the kinds of material I understand to be
embraced within that shorthand description; and perhaps I could never succeed in intelligibly doing so.
But I know it when I see it, and the motion picture involved in this case is not that” [19]. This phrase
“I know it when I see it” - cuts to the core of Type 1: the speaker is clearly and directly acknowledging
some sort of communicative limitation that is preventing him from clearly verbalizing what he knows.
As Stewart’s employment is fundamentally linked to his ability to closely read a text, analyze its
semantic particulars, and identify its contextual limitations, this is somewhat unsurprising.</p>
      <p>Unfortunately, in the vast majority of circumstances, people are not provided the tools and
opportunities needed for direct self-disclosure, and, absent either, they are much less likely to
understand that their failure to communicate is coming from an embodied way of knowing. This is
demonstrated in Nowe Ateny, the first Polish-language encyclopedia, where author Benedykt Joachim
Chmielowski penned a very abridged entry for “horse” consisting of one sentence: “jaki jest, każdy
widzi” [20]. This is usually translated to “everyone knows what a horse is.”</p>
      <p>Although “I know it when I see it” and “everyone knows what a horse is” communicate similar
ideas, there are significant differences in their tacit components. In the first scenario, Stewart removed
all the guesswork by saying the quiet part out loud: for some reason, I can’t tell you what I know.
Chmielowski is expressing something fundamentally different: I don’t need to tell you what I know. In
the first case, the speaker is aware that he is acting upon tacit knowledge to define a category. This
awareness is lacking in the second, and Chmielowski does not explain why, exactly, he believes we are
all on the same page. The social tacit knowledge being acted upon here is indirectly referenced but not
explicitly stated.</p>
    </sec>
    <sec id="sec-9">
      <title>6. Case study of Type 3: tacit knowledge indirectly expressed through verbal omission</title>
      <p>As Types 1 and 2 are reliant on self-disclosure, these forms of tacit knowledge can be identified in
verbalized language. In the first case, Stewart provides a relatively explicit admission; while he does
not use the actual phrase “tacit knowledge,” he describes the concept fairly well. In the second,
Chmielowski is less direct, but his phrasing strongly suggests a tacit knowing. Differences aside, both
authors’ phrasing is somewhat odd and prompts further exploration. With Type 3, that anchor is
removed and we are presented with a much more difficult challenge: we must discover what is missing
in what has been said.</p>
      <p>As I suggested in the introduction to this work, Jewish dietary laws are uniquely suited to this task
for two primary reasons. First and foremost, kashruth is a cultural knowledge system that has been
meticulously documented and studied. While the analysis of tacit silence is an innately speculative
activity, domains and systems associated with significant primary and secondary documentation require
us to make smaller conceptual jumps when connecting the dots. As kashruth essentially comes
prepackaged with a plethora of commentary and debate via the Talmud, we have a large body of
wellstudied reference materials to work with. Second, the interpretive activity central to this exercise is
mirrored in standard rabbinic practice, including the chavrusa style of informed discussion. According
to Steven Fraade, “One of the most celebrated aspects of rabbinic literature is its adducing of multiple
interpretations of scriptural verses and its valorizing of multiple legal opinions as expressed in debate
among the rabbinic sages” [21]. Rather than a disrespectful insertion into a world shielded from personal
opinion, this exercise can be viewed as an addition to this domain and its standard practices.

      <title>The problem with pigs</title>
      <p>When I ask most people to guess what makes something kosher, I tend to receive one of three
answers: 1) the food does not contain pork, 2) it does not mix meat and dairy, or 3) it has been blessed
by a rabbi. Interpreted generously, all three responses are partially correct. Yes, Jewish law prohibits
the consumption of pork, forbids the mixing of meat and milk, and requires the input of a rabbi - or
rabbi-adjacent specialist - at certain points in the food production cycle, but these comprehensive dietary
rules extend far beyond a single person or species to moderate the raising, processing, and consumption
of all crops, non-human animals, and the derivatives of both. Of these rules, sixteen apply specifically
to meat and animal products. See Table 2.</p>
      <p>Translations are taken from Forst [22]. “Source” refers to the origin of the dietary law and is divided,
also following Forst, into two categories: rabbinic and biblical. “Scale” identifies if the rule prohibits
the consumption of an entire kind/type, a specific part of a kind, or the mixing of different kinds and/or
parts.</p>

        <p>Based on biblical proclamations, bacon is indeed off-limits, but pigs are just one of four “unclean”
animals (beheimah temeiah) explicitly named in both Deuteronomy (14:6-8)
6. And every animal that has a split hoof and has a hoof cloven
into two hoof sections, [and] chews the cud among the animals
that you may eat.
7. But you shall not eat of those that chew the cud, or of those
that have the split hooves: the cloven one, the camel, the hyrax,
and the hare, for they chew the cud, but do not have split hooves;
they are unclean for you.
8. And the pig, because it has a split hoof, but does not chew the
cud; it is unclean for you. You shall neither eat of their flesh nor
touch their carcass. [23]
and Leviticus (11:7)
11. And the pig, because it has a cloven hoof that is completely
split, but will not regurgitate its cud; it is unclean for you. [23]
For an animal to be classified as “clean” (beheimah tehorah), they must meet two criteria, or simanim
(signs): they need to ruminate and have fully split hooves. Camels, hyraxes, and hares meet the first but
not the second; pigs meet the second but not the first.</p>
        <p>Notably, while the cloven-hooved species are presented as a trio, the pig is alone. However, within
the beheimah tehorah category, there is no additional hierarchy, and all four species are equally unclean.
And yet whenever I ask, “What foods aren’t kosher?” no one has ever replied, “Hyrax meat.” It’s always
pigs - and, for the most part, this seems to have always been the case. But why this incessant
preoccupation with pork?</p>
        <p>Kraemer explains that the “categories established by the Torah’s eating laws [...] reflect the values
- and even the categories - of the Israelite society in which these laws were promulgated.” Thus the
“key to interpreting the system,” and the pig’s place within it, is to “discover the manner in which the
animal taxonomy described in the Torah reflects the human society whose values it represents” [1]. Of
all the kinds listed, why have pigs maintained such a central position in this dietary ontology? What
damned place did the animal occupy in the minds of those dictating the biblical canon? Why was it not
the hyrax?

    <sec id="sec-11">
      <title>Unclean animals (and the people who eat them)</title>
      <p>Around the first century BCE, pork consumption rose among the general Palestinian population, a
trend linked to a combination of pragmatic and cultural pressures. With the Hellenization of the region
came the adoption of Greek, and later Roman, dietary customs, including their preference for pork [1].
“Thus, the abundance of evidence, both direct and indirect, supports the same conclusion,” Kraemer
explains:
when the common Palestinian Jew viewed the common gentile
eating meat at her or his table - in the first century BCE or of the
first century CE - that meat was far more likely to be pork than
anything else. In other words, of all the species marked off-limits
by the Torah’s legislation, the only one concerning which this
would be a difference on a regular basis was the pig. The rest
were primarily of academic interest, the pig was a presence and
potentially a temptation. [1]
When Jewishness seemed vulnerable to outside influence, meal patterns provided an opportunity to
pronounce and reaffirm one’s identity three or so times each day. Sure, the hyrax was deemed equally
unfit for Jewish consumption, but there was little use in emphasizing a kind of food that was seldom on
the table. Pigs, on the other hand, were a relatively abundant and culturally significant protein source
easily imbued with symbolic value.</p>
      <p>At the time these kashruth categories were codified, a rejection of pork was much more than a dietary
choice - it was a political statement. In Palestine during the first century BCE, pigs were not “unclean”
simply due to their nature or poor hygienic tendencies; rather, the animals unwillingly adopted a
symbolic association with the Hellenization of the region. You were not dirty for eating pigs - pigs were
dirty, at least in part, because of who was eating them. Eilberg-Schwartz has written in support of this
stance, claiming that these “dietary restrictions carve up the animal world along the same lines as
Israelite thought” (cited in Kraemer [1]), with the good, “clean” animals representing the Kingdom of
Israel and the “unclean” symbolizing the other. In an early iteration of “you are what you eat,” religious
authority used these classificatory divisions to guide the general population towards a life of moral
purity. “[Separate] from the nations, and do not eat with them” Abraham warned Jacob, “for their works
are unclean and all their ways polluted” (Jubilees 22:16). The pig was but an idol of this polluted society.</p>
      <p>Writing approximately a millennium after the formation of the Written Torah, the Sephardic
philosopher and theologian Maimonides commented on the kashruth of pork and proposed an
alternative origin to the law. In The Guide for the Perplexed (ca. 1190 CE), he offers a public health
justification for the prejudice against pigs, asserting, “The principal reason why the Law forbids swine’s
flesh is to be found in the circumstance that its habits and its food are very dirty and loathsome” [24].
This determination makes sense. As other rabbinic injunctions ban so-called “dangerous foods”
(sakanah), safety was clearly a consideration when crafting the food laws. However, when Maimonides
previously analyzed and discussed the nature of sakanah in Mishneh Torah (ca. 1170-1180 CE), this
danger was of a different variety - namely snakes and their venom. Stabbings were also apparently of
concern, and the reader is warned that “one should not stick a knife into an etrog2 or into a radish, lest
a person fall on its point and die” [24]. Pigs, however, are not mentioned.</p>
      <p>While Maimonides's claim to the “loathsome” nature of the pig appears to mirror common rhetoric
unfairly casting the animal as an innately dirty creature, this alone does not justify their exemplarily
poor biblical and societal status. For one thing, if there was something especially egregious about pigs
themselves that rightfully earned them such a terrible reputation, this reasoning would have likely been
dictated directly in the Talmudic texts or its commentaries, both of which eagerly cover the most
unlikely and obscure of scenarios (e.g. death by etrog stabbing). The ancient sages and later
commentators, including Maimonides, neglected to meticulously dissect very few of the Torah’s
concepts and terms, and yet the meaning behind moralized phrases such as “clean” and “unclean”
continues to be debated by modern Jewish Studies scholars.</p>
      <p>I would argue that this failure to explicitly define such foundational categories suggests a tacit
understanding that was either impossible to articulate or otherwise rooted in an implicit social value.
As Culler explains, “acts of imposition are themselves made possible by the situations in which they
occur, and meaning cannot be imposed unless they are understood, unless the conventions which made
possible understanding are already in place” [25]. Without a preexisting understanding of pork’s
symbolic and material value, the prohibition would likely not have had such a lasting impact on Jewish
dietary identity.</p>
      <p>Maimonides’s public health argument is not entirely unreasonable, but some of his other statements
suggest a deeper, more tacit factor is at play here. Later in his Guide, he writes that “[if Jews] were
allowed to eat swine’s flesh, the streets and houses would be more dirty than any cesspool, as may be
seen at present in the country of the Franks” [24]. This appears to be his true justification: if we were

to eat pigs, we would inevitably become like the Franks. Either the Franks are loathsome because they
consume pork, or the Franks are loathsome, so, therefore, they eat pigs. Both logics are probable, but it
ultimately does not matter which is the case. In both scenarios, the tacit essence of the animal’s
uncleanliness can only be explained through the habits of the Franks. Viewed this way, pigs become a
proxy for the people that consume them.</p>
      <p>Support for this interpretation is provided by Klawans [26], who presents a schema of Jewish purity
that further divides Jewish law (halacha) into subcategories based on each law’s moralistic or ritualistic
purpose. He notes that while kashruth directions are sourced from both Leviticus and Deuteronomy,
most laws related to ritual are covered in Leviticus 12-15 and most based on moral arguments are
covered in Leviticus 11. Although there is an obvious overlap between the two categories, the division
makes sense when one remembers that a significant portion of ancient Jewish worship manifested
through sacrificial Temple offerings. So while moral purity undeniably impacted ritual practices and
vice versa, Klawans notes that consumption of the “impure foods” listed in Leviticus - including the
pork prohibition at 11:7 - is broadly prohibited and not simply “defiling” for ritualistic purposes [26].
Thus the “outright prohibitions of eating certain foods function more like a moral defilement than a
ritual one” [26].</p>
      <p>At the end of the day, this seems like a lot of upset over one animal. The ancient rabbis likely had
more pressing concerns to contend with, and Douglas notes that it “is not in the grand style of Leviticus
to take time off from cosmic themes to teach that these pathetic creatures are to be shunned because
their bodies are disgusting, vile, bad” [27]. Rather, their persistent emphasis on pigs gestures towards
an inherent and parasitic vice to be avoided at all costs.</p>

      <title>7. Conclusion: Tacit traces</title>
      <p>The methodological framework proposed here seeks to illustrate one way KO scholars might identify
tacit knowledge and its silent influence. As an embodied phenomenon, tacit knowledge cannot manifest
through straightforward language, requiring descriptions that are indirect and often more ambiguous.
Here, I have proposed three categories of tacit types based on varying degrees of self-disclosure and
verbal omission, an approach that seeks to identify tacit knowledge through either the acknowledgment
of the original speaker or the gaps in their documented narratives. My selection of the first metric
(selfdisclosure) is based on the perspective that, while tacit information cannot be articulated, an individual
may nonetheless be aware that certain cognitive and linguistic blocks are present. Self-disclosure offers
an opportunity to describe one’s experience in more roundabout terms; researchers may collect this
information through qualitative interviews or, in the absence of the original subject, using forms of
document and discourse analysis. The second metric (verbal omission) relies heavily on tools from
domain analysis to develop a foundational understanding of the ideas, terms, and topics central to a
knowledge community. From this thorough understanding of discursive norms, researchers may suggest
what expected information appears to be absent.</p>
      <p>Due to spacetime limitations, we are unable to return to a gone place or time to inquire about its
classificatory habits. This poses a methodological challenge for KO researchers attempting to
understand historical organizational practices and their tacit components. Without the ability to ask
questions directly, our only option is to find clues in the historical record and fill in the gaps to a
reasonable extent. Of course, we will never truly understand what it was like to be a particular person
in a particular place at a particular time, and with the death of a person goes the only source capable of
testifying to their tacit knowledge. Empathy can only go so far, and “a trace always [refers] to another
whose eyes can never be met” (Derrida 1995, 84). But, in the sharpening of our own eyes, we can locate
evidence of this embodied experience in the marks left behind. The body dies, but it always leaves a
trace.</p>
