The Open Microscopy Environment (OME) is a consortium that produces open-source tools and format standards for microscopy data. The OME model is a speci cation for sharing biological imaging data in two parts: metadata as OME-XML and binary data as OMETIFF. We built an OWL ontology translation of the OME-XML speci cation called OME core ontology so as to catch up with the rapid progress and diversi cation of imaging technology and to facilitate integrated analysis with various life science data. This poster presents the details and status of the ontology, associated tools, and future plans.
Imaging is one of the fundamental techniques and data types for understanding life phenomena intuitively through human vision. Because imaging data itself does not describe explicit knowledge, imaging metadata is fundamental to enable data sharing and integration of multi-modal imaging data with various other types of life science data.
Having multiple life science centers and laboratories, RIKEN employs various imaging apparatus covering a comprehensive range of scale, from organelle through organ to organism. For integrating the imaging data produced and the experimental conditions, a multi-modal ontology for electron microscopy, X-ray computed tomography and magnetic resonance imaging was developed as an OWL-based extension of the OME data model1 which describes imaging metadata for OMERO2, a de facto-standard imaging tool. Having con rmed the core ontology through this multi-modal extension in di erent practical research projects, the OME consortium has adopted the newly developed OWL-based OME model as an o cial companion to their XSD-based model.

The OME core ontology is a translation of the OME-XML format of the OME
data model version 2016-063 that covers all its concepts and attributes. The
ontology contains 130 classes and 210 properties. In addition, we implemented
tools written in Java and a spreadsheet template for describing RDF data using
the OME core ontology. The data converter is a tool for converting OME-XML
format data into RDF using the OME core ontology. Another tool, the OME
compatibility checker, determines if the given ontology includes OME core
subclasses and sub-properties. This checker is used for the 4DN-OME ontology for
con rming if it is an extended ontology of the OME core ontology [
Finally, a spreadsheet template facilitates the users' description of RDF data
for entry in the RIKEN MetaDatabase [
Herein, we report our progress on the development of the OME core ontology and tools. With the publication of the ontology, members of the bioimaging community can develop an extended ontology converting the complete original imaging environment.Though the OME core ontology is designed for bioimaging, it can be connected to healthcare metadata such as DICOM data. Further, the distribution of imaging data in a FAIR representation accelerates advanced data analysis, critical for Open Science. Our goal is to enable integrated multi-omics knowledge analysis, arti cial intelligence-supported image diagnosis, and scalecontinuous image analysis as well as the realization of a standardized image analysis platform based on OMERO technology.
