Modeling, Methods, and Content

The IDS-ADI Modelling, Methods & Content team ("Modelers" for short) is focussing on defining all modeling and methodology aspects of Part 7 independent of implementation. Part 7 supports all levels of modeling from from business short cuts to explicit Part 2, with methods for mappings between these, in sufficient rigor and formality to enable implementation and reliable lifecycle management in Part 4 reference data.

This is the modelers home page and should lead anyone to all aspects of this scope.

For implementation & technology aspects which will be covered by Parts 8 and 9 refer to the [Implementors] home page.

For arrangements to manage this scope beyond the life of the IDS-ADI projects, refer to Part 5 on referebce data rules, Part 6 on reference data administration, and the MMT SIG homepage currently at the POSC Caesar main website.

Templates >>> add start page (use TemplateGenerics as basis)

Identification >>> add start page (leading to specific URI requirements)

Below here >>> to be further re-organized following the above.

Navigation >>> add suitable TracNav, as well as page index / bookmarks.

Ongoing activities

  • We have begun publishing documentation on ISO 15926 templates, as developed in the IDS-ADI project. Templates are patterns for facts for which definitions are stated in terms of rules. This provides for a convenient and precise interface, and is intended to be used for creating and maintaining ontologies that conform to the ISO 15926 standard.

Template Development

Templates may be used to define and represent both reference data and project data. The following figure illustrates the relations between the languages of ISO 15926 Parts 2/4 and the template language of Part 7. In brief: Part 2 corresponds to a Description Logic (DL) TBox, i.e., classes and relations. Part 4 and other reference data populate the Part 2 structure with individual instances, a DL ABox. Templates according to Part 7 require a much more expressive, first-order language.

Look at the bottom of this page, and of TemplateDescriptionID, for ongoing discussion on the characterization of ISO 15926 templates. A document describing the current list of templates defined in the IDS project, with roles and brief definitions in natural language, can be found as an attachment to the Intelligent Data Sets Prototype page.

The following is a list of pages that describe individual templates, with definitions, diagrams, and so forth.

Tools in this Trac

ISO 15926 Diagrams.

The Wiki provides for entering diagrams of ISO 15926 models, using a simplified set of xy-pic commands; see ISO15926Diagrams. Examples can be found in ISO15926Diagrams_BoltSet, ISO15926Diagrams_Weights.

Complex content using LaTeX.

This Trac supports entering content in LaTeX format, using the LatexEquation plugin. This is useful for entering first-order formulae, and diagrams.

Macros for fetching reference data.

A facility for dynamically pulling content from the Reference Data Library for graphical display on Trac pages, using XSLT, graphviz, and the macrochain macro, is high on our wishlist. For the time being, only the XSLT macro works with Trac 0.11.

Source material


Presentations from Semantic Days 2008 are available in Powerpoint format. We intend to provide PDF formatted copies shortly.

  • A Tutorial on semantic technology, with special focus on templates for ISO 15926. Download slides
  • A presentation of SIG MMT, describing this Trac and the need for template interfaces for creating reference data. Download slides
  • Under development, an overview of ISO 15926 reference data resources contains a series of resources (files and links) related to Models, Methods and Technology for ISO 15926. Please note that access to these resources currently requires logging in, that display requires Internet Explorer, and that some of the links are limited to internal DNV use for the time being.
  • Take note: A new paper called Structured Objects in OWL (Motik, Cuenca Grau, Sattler) is extremely promising with regard to finding a more natural and powerful language for defining templates. Stay tuned.
