Hi all, The CellML 1.1 specification says:
" 6.5.3 Groups must not imply metadata information Modellers must not use CellML groups to associate properties or classification information with sets of components. The metadata functionality is the proper method for making such associations. This increases the chance of that information being used by a range of CellML processing software. " If extension groups cannot be used to imply metadata or mathematical information, then there is not really anything left for them to imply. I think that we should do one of the following: 1) Non-standard relationship types be disallowed, and only encapsulation and containment be kept (encapsulation does affect the mathematical formulation of the model, while containment is really metadata information), or perhaps only encapsulation should be kept, with containment data represented in metadata, or, 2) Allow groups to be used for metadata information, but in the informatively annotated specification encourage the CellML community to standardise on exactly how a certain type of metadata should be represented (this is required whether RDF/XML or groups is used to express the metadata anyway). I would welcome any opinions that anyone might have on this.
