I will be more than happy to help with the evaluation part.

Subject: [ontology-summit] Clinic proposal: Verification and quality measurements for ISO 15926 reference data
Ontology Clinic - A: Verification and quality measurements for ISO
15926 reference data
This ontology clinic is aimed to the evaluation of publicly available ISO 15926 reference data viewing it as ontology for engineering domain. We will look for compliance to upper ontology constraints, diagnose problems in reference data, evaluate ease of understanding and use of existing data, and make suggestions for ontology improvement. Another goal is to apply formal ontology quality metrics for data in question..
The effort will develop rules and algorithms to support generic verification tests, and also attempt to invent and implement specialized checks and quality metrics for ISO 15926 reference data.
The ISO 15926 is a standard for engineering data integration, sharing, exchange, and hand-over. The standard defines a generic data model as an upper ontology for an engineering domain. Extensive Reference Data Libraries (ontology data) for process plants are developed by community of users, which includes equipment manufacturers, engineering companies and owner/operator companies in oil and gas, nuclear power, petrochemical industries, and others. Standard development and application is jointly managed as JORD project by two industry associations: POSC Caesar Association and FIATECH.
Upper ontology of the ISO 15926 is publicly available as an OWL representation of ISO 15926-2 at
http://rds.posccaesar.org/2008/02/OWL/ISO-15926-2_2003 (see https://www.posccaesar.org/wiki/ISO15926inOWL for more details).
JORD Reference Data Library is available as a reference data service:
- the human browser access & query page is http://posccaesar.org/endpoint/
- the SPARQL endpoint is http://posccaesar.org/endpoint/sparql
A snapshot file with full content of an endpoint is available for download at http://rds.posccaesar.org/downloads/PCA-RDL.owl.zip .
Various resources for study of ISO 15926 are available from http://www.infowebml.ws/, http://www.15926.info/, http://www.15926.org/ (see self-education guide at http://levenchuk.com/2012/10/01/iso-15926-self-education-sequence/).
Evaluate publicly available ISO 15926 reference data:
- compliance to the best practices of ontology engineering;
- compliance to logical model and upper ontology constraints;
- diagnose problems in reference data;
- make suggestions for data improvement;
- evaluate ease of access, understanding and use of existing ontology data.
We'd also like to attempt calculation of ontology quality metrics for ISO 15926 upper ontology and Reference Data Library in various software environments or by standalone tools. We can use existing methodologies (like OntoClean, OQuaRE or OntoQA) or brainstorm for new metrics.
Availability of data in OWL, RDF/XML and at a SPARQL endpoint allows the use of both public and proprietary tools in this clinic project.
General purpose ontology management and Semantic Web tools can be used along with special purpose tools developed for work with ISO 15926 data (like iRING Tools http://iringug.org/wiki/index.php?title=IRINGTools or .15926 Editor http://techinvestlab.ru/dot15926Editor).
Project initiators are TechInvestLab.ru, Moscow (Russia) based company, developer of .15926 software environment. Another team of tool developers from Moscow (http://agentlab.blogspot.ru) has also expressed interest in participation.
We are looking for collaborators – ontology evaluation experts commanding any generic or specialized software tools to work on proposed ISO 15926 datasets. We will welcome software tool developers willing to show use of their instruments for project tasks.
Our own tool .15926 Editor is freely available (see link above), well documented, is designed for exploratory programming and includes examples of use for data verification. Basic knowledge of Python programming language will be enough to join us in the project with this tool.
We will be happy to provide office space for real world collaboration in Moscow, well connected to the virtual environment of Hakathon.
We are panning to get:
- the list of “hard” problems (errors, inconsistencies, missing data,
etc.) in existing JORD Reference Data Library;
- characterization of any “soft” problems with data identification, availability, understandability, etc.;
- adopted or new ontology quality metric methodologies for ISO 15926 ontology;
- ontology quality metrics calculated for JORD Reference Data Library;
- suggestions for improvement of data consistency and quality in JORD Reference Data Library;
- algorithms, scripts, software tools proven to be useful for verification and quality assessment of ISO 15926 data, made available to ISO 15926 community.
Project results will be presented 11-14 of April at ISO 15926 round table during 4th annual Systems Engineering Challenges workshop of INCOSE Russian chapter.
