      <title>FORWORD</title>
      <p>This document describes our path and the economics of the
interdisciplinary Interoperability Network, a so called
‘Internet of Actors’. We, the authors, have our background
in business mathematics and business informatics. In order
to grasp the manifold tasks and to develop the methodical
and technological concept of the Interoperability Network,
it was important for us to expand our circle of consultants
in order to capture and take all requirements and
development trends into account. Our closest consultants
are therefore recruited from the following areas of
expertise:
In preparing this document, we have not only felt the
language barrier between the classical languages, but
above all between the different subject areas. There are
numerous cases in which, depending on the discipline,
sometimes even within a discipline, the same subject
matter has different names. These differences have
repeatedly led to long discussions and an intensive search
for the "right" word. We hope that we have always found
it in this document.</p>
    </sec>
    <sec id="sec-2">
      <title>1 Initial Situation</title>
      <p>Intra- and inter-company workflows are changing from
classic, predefined, inflexible business processes to global,
agile value networks. Man, machine and software modules
work and communicate integrated and coordinated on
application level to achieve their objectives together
(interoperability). This requires a new dimension of
agility, speed of change, participation and autonomy in
business IT.</p>
      <p>The so-called platform economy, based on geographical,
sector-specific and/or proprietary approaches, leads either
to the formation of monopolies (B2C such as Google,
Amazon, Facebook) or to a multitude of platforms (B2B).
However, all existing B2C platforms show that a platform
can only be fully effective if almost all users use the same
platform. The B2B platforms enable communication for
their respective sub-communities but are not interoperable
with each other.</p>
      <p>
        This interoperability, which is so necessary, does
not exist today [...]. However, there are also
market participants who expect benefits from this
obstacle: »Those providers whose systems
determine the market are generally favoured by
this deficit. Here interoperability is an important
mechanism for reducing existing economic and
technical dependencies, especially for the
German, predominantly medium-sized industry«.
(
        <xref ref-type="bibr" rid="ref1 ref6">1</xref>
        )
The above quote from Bitkom is not only valid for the
German economy but also for the European and even
global economy and should be a wake-up call for most
corporations. For the business sector this means absolute
dependence on the preferred platform provider. (
        <xref ref-type="bibr" rid="ref3">2</xref>
        ) In
addition to this dependency, a second situation
automatically arises that threatens the existence of any
enterprise, since a location outside the enterprise is created
where all data can be collected and evaluated across all
enterprises. The platform providers have sovereignty over
everything that happens on these platforms. Since platform
customers have no say and no participation, this model is
developing more and more into a serious challenge for the
digital transformation and Industry 4.0.
      </p>
      <p>Particularly in the business sector, there is often the
additional demand and necessity to give more autonomy to
the acting employees or divisions of the company to
collaborate on the solution of their topics. There is also an
increasing need to equip machines/devices with more
autonomy in accordance with today's technological
possibilities.
We want to ensure and sustain the entrepreneurial diversity
and sovereignty of the participants in the digital economy.
The growing social sensitivity towards platforms leads to
the conclusion that social development lies in a digital
Interoperbility Network and will thus lead to a network
economy.</p>

      <p>Network commerce has consequences that go far
beyond just a business model.</p>
      <p>Markets are based on mistrust,
Networks on trust.</p>
      <p>Markets are based on the pursuit of
selfinterest,
Networks on shared interests.</p>
      <p>Markets are arm‘s-length transactions,
Networks are intimate relationships.</p>
      <p>Markets are competitive,</p>
      <p>
        Networks are cooperative. (
        <xref ref-type="bibr" rid="ref5">3</xref>
        )
The above quote from Jeremy Rifkin shows in an
exaggerated way the differences between markets and
networks. In the network economy, we are not only talking
about a single software application, but an infrastructure
for many/all applications.

    <sec id="sec-5">
      <title>2.1 Methodical Technical Characterization of Interoperability</title>
      <p>The definition of a network also applies to a
(softwarebased) interoperability network:</p>
      <p>
        The term network is generally used to describe
structures and systems that consist of a set of
elements (nodes) that are linked together via
connections. [...] The simple principle of nodes
and connections allows a multitude of different
architectures. Networks form open structures that
are able to expand without boundaries and to
integrate new nodes as long as they are able to
communicate within the network. (
        <xref ref-type="bibr" rid="ref9">5</xref>
        )
Both (software) nodes and connections must be defined in
the interoperability network.
      </p>
      <p>
        The EU has generally defined interoperability as follows:
Interoperability is the ability of organisations to
interact towards mutually beneficial goals,
involving the sharing of information and
knowledge between these organisations, through
the business processes they support, by means of
the exchange of data between their ICT systems.
(
        <xref ref-type="bibr" rid="ref2 ref7">4</xref>
        )
In addition to the written definition, we also see in Figure
2 the profound meaning of the term interoperability for the
digital world. The interdisciplinary stack for
interoperability is created.
A distinction is made between four layers of
interoperability. Although the layers build on each other,
the aim is to develop the layers as independently as
possible.

        <p>The layer at which the legal framework is
coordinated by the parties involved. For the digital
world, the legal framework is also described in
semantics. From this follows automatically the
requirement on the involved parties to determine
these rules so exactly that the guidelines allow a
technically distinct processing.</p>
        <p>The technical and semantic interoperability layers and
their derived scope of services thus represent the software
infrastructure for all layers in the EU Framework. This is
the prerequisite for global value creation networks.</p>

      <title>2.1.1 Technical interoperability with its communication at application level</title>
      <p>Internet of Things, Internet of Everything, Industry 4.0,
Networked Economy and Digitalization imply the vision
of a global communication network on application level
(Interoperbility Network). The particular challenge is the
inter-company communication, which requires the
interoperability of all digital network nodes. Global
interoperability can only be achieved through
standardization.</p>
      <p>Over the past four decades, the telecommunications
industry and the IT industry have shown that standardized,
global communication networks generate enormous
wealth effects. The Internet and the global mobile network
are the most prominent examples. Global communication
networks fulfill two mutually dependent requirements,
they are supported by a largely democratically organized
community, and the technologies and architectures used
offer members of the community the opportunity to
participate.</p>
      <p>A sustainable digital, global communication infrastructure
on application level (Interoperbility Network), which
enables its users to participate, can be identified by the
following criteria:
•
•
•
•
scientifically proven
unique, modular, standardized, interoperable,
democratic, regulated, non-discriminatory
decentralized, horizontal
Standardization in the field of communication technology
has always led to a great leap in the dissemination of
technological progress in recent decades. At the same time,
standardization has always laid the technical foundation
for a new market. Based on a common standard, a wide
variety of devices and software solutions are developed
that are interchangeable thanks to standardized
communication. Standardization prevents the lock-in
effect to hard-and software vendors (vendor lock-in) and
at the same time guarantees the diversity that is desired and
necessary in social policy. Examples are the GSM protocol
for mobile communication as well as the TCP/IP protocol
for the expansion of the Internet.
At the same time, however, the scope and complexity of
the requirements increased steadily. Another driver for
increased complexity will be the IoT with its trillions of
software modules just as the ever faster change of business
models requires a new dimension of software agility.
In order to overcome this increase in complexity and
avoid the lock-in effect of the platforms, an Interoperbility
Network must be created in which the digital nodes
connect via a universal and standardized communication
protocol.</p>
      <p>In an Interoperbility Network, software applications are
created by connecting autonomous software nodes. This
means a paradigm shift for the development of software
applications. The focus is no longer on object orientation,
but on the communication of the digital nodes.</p>

      <title>Development</title>
      <p>The creation of software has developed considerably over
the past decades and has become simpler in many ways.
(see also Figure 4) In order to program a fixed scope of
services, only a fraction of the effort and knowledge
required in the 1970s and 1980s is required today.</p>
      <p>Programming languages have become more powerful, and
object orientation in particular has led to a considerable
increase in performance. Today, small and singular tasks
can be programmed and solved very quickly.</p>
      <p>Due to the increasing complexity of business
requirements, the description of requirements segment is
increasing in relation to total effort. (see also Figure 4) The
same effect can be seen in the segment of transformation,
which has expanded considerably over the decades due to
more complex tasks, larger project teams, the dissolution
of software monoliths into smaller service units and the
need for integration into existing IT landscapes. In the
segment of pure programming, on the other hand, the
relative effort has decreased considerably in recent years,
also due to the larger performance volume of programming
languages and their tools.
Above functionalities ensure that a software application is
established in the Interoperbility Network and that the
Description of Requirements and the Programming &amp;
Execution segments merge into a new segment called
Executable Description. The transformation segment is
simplified and therefore requires much less effort.
Based on the specifications made in the areas of technical
and semantic interoperability, the organisational and legal
requirements are identified, defined and implemented.</p>

      <p>The technical and methodological approach of an
Interoperbility Network is supplemented by economic and
social considerations. Standardization is an important
prerequisite for global interoperability.</p>
      <p>An Interoperbility Network is like a digital economic
space with a single type of product - software.</p>
      <p>It needs democratic structures for standardization,
participation of users and ongoing technical and economic
development. This must be ensured by an ordoliberal

of successful digital communities can serve as guidelines,
such as those of the IHE community in the healthcare

•
•</p>
      <p>Participaton: Membership should be open to all
interested parties. Private sub-communities (e.g.
companies, countries, etc.) could adopt their own
rules and structures within the framework.
Transparency: Fundamental information on
governance, activities and decisions should be
accessible to all users.</p>
      <p>Representation of users: The Governance and all
administrative activities are representing the will
and the needs of a wide range of users
Scientific support: Consulting accompaniment and
partnership by scientific organizations are of crucial
importance to ensure the further development to the
benefit of the users.</p>
      <p>Representation of the industry: The commitment of
providers in the IT industry (hardware, software,
system integration, IT operations) is substantial for
the marketability of an Interoperability Network.
Non-partisanship and balance of interests: No
special interest should dominate the
decisionmaking processes.</p>
      <p>Efficient decision-making structures: Decisions
should be taken through procedures that ensure that
all opinions are taken into account. There should
also be a dispute settlement process.</p>
      <p>Consensus: In all decisions, the greatest possible
consent by users should be sought.</p>
      <p>Competition: Users of an interoperability network
include business organisations that compete directly
with each other. The governance of an
interoperability network must therefore ensure
compliance with the relevant legal requirements,
including antitrust law.</p>
      <p>Relevance: The governance of an interoperability
network should pay particular attention to the
applicability of the technologies and structures
developed.</p>
      <p>Effectiveness: Decisions should be designed in
such a way that they can be implemented as quickly
as possible.</p>
      <p>Interoperability orientation: Sustainable
Interoperability should be given the highest priority
in the further development of an Interoperability
Network.</p>

      <title>Interoperability Network</title>
      <p>An Interoperability Network becomes a value creation
network through the economic activities that take place on
it. This value creation network with its users and rules can
be completely digitally modeled. It ensures that all
agreements are executed as negotiated between the users.
The digitization of the management of an Interoperability

marketplace to enable users to trade software applications
and business choreographies. All functions and processes
on such a marketplace can be executed digitally.
Standardization and interoperability ensure that by design
interoperable software applications are provided (technical

The associated difficulties of valuation and remuneration
mechanisms deserve special attention.</p>
      <p>In order to address the problem of the valuation of
software, the valuation for the use of the Interoperability
Network could consist of two components, a base
component and a market component.</p>
      <p>A base component can be automatically calculated using a
predefined algorithm and distributed to the users involved
in development or operations. Each software application
should have a base component to ensure a fair minimum
remuneration of the users.</p>
      <p>A market component that can be freely negotiated among
all participating users of the Interoperability Network can
be added. This process can also be implemented largely
digitally.</p>
      <p>All rules and processes for valuation should be
continuously adapted by the members and committees of
the Interoperability Network.</p>

      <p>An Interoperability Network should provide an attractive,
fair and performance-oriented framework for all users.
By establishing global, interoperable B2B value creation
networks, the size of the expected economic area can far
exceed that of the existing Internet. It can be assumed that
an increasing migration of proprietary IT systems and
platforms into a global Interoperability Network will take
place. This can create a global Network comparable to the
Internet or mobile networks.</p>
      <p>In the long term, the available global market potential of
an Interoperability Network can reach the aggregated
global market volume forecasts for the IoT, Industry 4.0
and digitalization in general. The level of welfare gain for
the international community can only be imagined and
should be many times higher.</p>
      <p>A global Interoperability Network offers attractive
strategic investments in a sustainable ordoliberal digital
space. Users maintain their independence, and investors
make targeted long-term commitments.</p>

      <title>Interoperability Network</title>
      <p>
        In order to achieve the characteristics of the
Interoperability Network, actnconnect has developed a
modular software network architecture based on scientific
methodologies. The core of this network are the nodes we
call Smart Actor (
        <xref ref-type="bibr" rid="ref14">9</xref>
        ). We therefore call the Interoperability
Network 'Internet of Actors' (IoA).
      </p>
      <p>
        Software applications on the Internet of Actors consist of
any number of independent and interoperable Smart
Actors. Software applications are created agilely and
dynamically using the ability to connect Smart Actors in a
standardized way. This results in cross-company value
creation networks. (see also (
        <xref ref-type="bibr" rid="ref14">9</xref>
        ))
Besides the governance and the economic view on the
Internet of Actors, we will focus in particular on the
following for the remainder of this document:
•
•
the technological developments leading to the
decentral and interoperable Internet of Actors, and
the possible framework to ensure fair remuneration
for the services provided by each member.

is described in the white paper "Internet of Actors, a
Peerto-Peer Value Creation Network" (

        According to Figure 4, column "Communication", the
segment of transformation is minimized despite the
increasing complexity of the requirements because, with
the help of the modular software design and the semantics
of this modular software design, the structure and
communication of each software node is unified and
standardized. We call this semantics "Internet of Actors
Notation" (IoAN). As a result, the IT knowledge required
is considerably reduced, because the IoAN is a
straightforward semantic for describing business
requirements which enables immediate execution in the
SmAOS. (Turing complete (
        <xref ref-type="bibr" rid="ref14">9</xref>

      </p>
      <p>Many communicating Smart Actors result in a software
application or what we call a business choreography. (see
also Figure 7)
Autonomous systems such as Smart Actors therefore no
longer require an orchestrating body. This characteristic
leads to the name Business Choreography. Each Smart
Actor can be used in 1 to n business choreographies, and
the SmAOS identifies potential communication partners
automatically. This will lead to a very high re-usage
probability and thus to a high number of uses.</p>
      <p>The IoAN's scope of services is synchronized with that of
the Smart Actors and SmAOS building block system, so
that any complex and interoperable business
choreographies can be created as value-added networks.</p>

      <title>5.3 Interoperability in the Internet of Actors in all Layers</title>
      <p>Summarising the previous chapters, we see that the issue
of interoperability, as elaborated by the EU, has not only
been met, but in some respects further completed. From
the perspective of the Internet of Actors, the definition of
interoperability is then as follows:</p>
      <p>Interoperability means that software building blocks
can communicate with each other according to the
agreements of the partners and work together towards
common goals. This is independent of the producers of
software building blocks involved. It includes
•
•
•
communicating peer-to-peer with
each other,
working together as intended, even in
complex, global value creation
networks and business processes, and
supporting and enabling
collaboration between man, machine
and software.
A core feature of business choreographies is that all Smart
Actors are autonomously acting units. This also implies
that each Smart Actor has access to all information about
its communication behavior and all required rules.
This results in the following implementation and extension
of EIF's interoperability when using the modular software
system: (see also Figure 8)
•
•</p>
      <p>Technical Interoperability is ensured in the IoA by
the modular system with the structure and
definition of the Smart Actors, together with the
RBI as communication protocol and the SmAOS.
Semantic Interoperability is ensured by the IoAN
semantics with complete synchronicity to the
technical structure in combination with immediate
executability (Turing complete).
•
•</p>
      <p>Organizational Interoperability is achieved when a
business choreography is agreed between all
participants and used in the IoA.</p>
      <p>Legal Interoperability is achieved when legal
requirements are translated into clear rules in a
business choreography and these become part of the
relevant Smart Actors.</p>

      <title>5.4 Tiers of the Internet of Actors</title>
      <p>The IoA in its structure and the used methods results in the
development of four Tiers for business concepts. (see also
Figure 9)</p>

      <title>Internet of Actors and their Tasks</title>
      <p>From a business point of view, the first thing we notice in
Figure 10 is all Tier-C participants. At this level,
domain-specific business knowledge is necessary. This is
where the contextual structure of the to be created
domainspecific value creation network is designed and defined.
The required Smart Actors are selected with a matching
process or produced in Tier-B. A lively exchange and
communication between the aadjacent levels is
indispensable.</p>
      <sec id="sec-30-1">
        <title>Tier-A</title>
        <p>At this level you will find all Smart Actors and Business
Choreographies that aim to create tools for the
Interoperability Network, e.g. for modeling,
choreography, management, quality assurance, selection,
accounting, etc. The Smart Actors and business
choreographies of this Tier are mainly used across
domains. However, domain-specific tools can also be
created.</p>
      </sec>
      <sec id="sec-30-2">
        <title>Tier-B</title>
        <p>At this level, the Smart Actors are developed for each
individual domain. A domain can be an industry as well as
a defined subject area. However, a Smart Actor created for
one domain can also be used in all other domains.</p>
      </sec>
      <sec id="sec-30-3">
        <title>Tier-C</title>
        <p>Based on the Tier-B domains, in Tier-C the business
choreographies of the respective domain are compiled
tested and executed.</p>
        <p>For better orientation, we have assigned the roles
commonly used today in the process from management
consulting to programming to the above Tiers in the IoA.
See Figure 9.
Tier-B and -C use the Smart Actors and business
choreographies of Tier-A as tools for their work. From
Base to Tier-C, this distribution of tasks will result in a
decreasing need for expertise in the methodologies of the
Interoperability Network. However, an in-depth exchange
on the business requirements will be necessary to ensure
the further development of the Base and the Tier-A.
Each member of the IoA Community can take on any role
depending on their competencies. There are the roles of
customer/user and, as shown in Figure 10, developer,
producer and business choreographer.</p>

      <title>6 Conclusion</title>
      <p>
        However, a universal plug-and-play in Industry
4.0 is an illusion. There will be no Industry 4.0
standard in the near or distant future to ensure
universal interoperability for machines and
equipment of all kinds. Even the meanwhile
intensified cross-industry standardization efforts
cannot and will not achieve this. (
        <xref ref-type="bibr" rid="ref1 ref6">1</xref>
        )
This document shows that the technological development
has overtaken the above statement.
      </p>
      <p>The next evolutionary step in the standardization of
communication is the interoperability of software
applications. With this, the development of a global
Interoperability Network can now be initiated.</p>
      <p>We believe that for the global community the digital
economic space of this Interoperability Network will be
the democratic alternative to the platform economy, Open
Source or Open API initiatives.
We call such global Interoperability Network the 'Internet
of Actors'.</p>
      <p>In order to ensure technical and economic sovereignty for
the users of the Internet of Actors, a scientific foundation
of the used technologies and the rigorous decentralization
of all activities are required. This is supported by the
inherent interoperability of software applications and the
transformation from programming to modelling. The
Internet of Actors software architecture ensures maximum
automation and scalability. The result is software
interoperability by design.</p>
      <p>An ordoliberal framework ensures sustainable governance
and fair remuneration for the services provided and used
by the users of the Internet of Actors.</p>
      <p>Communication itself represents a large part of economic
activities. With the Internet of Actors, a global trillion
USD eco-system is emerging which offers previously
impossible efficiency gains for the benefit of common
welfare. The avoidance of monopolies and dependencies
alone justifies the efforts to build it.</p>
      <p>We invite all players in scientific, economic and political
life worldwide to play an active role in shaping the Internet
of Actors.</p>
