A quick status report to you: We have summarized and discussed internally the Plant Lifecycle model and the Class model, and made improved models. I made them into new summarized topics, and I intend to lock the current topics to switch over to the new summaries. This will be done when a number of p...

The proposed Revision of Class model can be viewed here: http://www.15926.org/publications/general-discussions/class-model/index.htm Summary: This model is used to solve the problem of class revision.

In summary, the difference between the corrected template model in ISO 15926-8 and the proposed template model, is: The classes starting with "RDL" are out, The class Template specialization with its properties hasSuperTemplate and hasSubTemplate is out, and Classes Specialized Template and Proto Te...

Hans uses the term "the RDL" for any ISO 15926 compliant triple store with web service endpoint. He is right to do so. The term used for "THE RDL" in part 8 is the Core Library or Core RDL. Indeed the Core RDL only has core classes and reference individuals (but much more that the part 4 spreadsheet...
