The use of non-odf or foreign elements in Calligra can be discussed more generically. Calligra should discuss whether it save documents as OpenDocument document or as OpenDocument Extended document. An OpenDocument Extended document may contain foreign elements and attributes, whereas an OpenDocument document may not. OpenDocument document and OpenDocument Extended document are defined in section 2.2.1 and 2.2.2 of the OpenDocument Format 1.2 part 1 standard. According to the specification, an ODF consumer *shall* be able to parse and interpret OpenDocument documents and *should* be able to parse and interpret conforming OpenDocument extended documents. If the Calligra community chooses to write OpenDocument Extended documents, the current situation is fine. If the Calligra community, chooses to write OpenDocument documents, the foreign calligra:* attributes are not fine. However there is a workaround: currently the calligra:* attributes are used on draw:path and on styles. Both these elements have identfiers by which they can be referenced and annotated with RDF. We could choose to write additional information as RDF instead of foreign elements. By doing so we can claim to write OpenDocument documents instead of OpenDocument Extended documents. I think that for now, we can stay with writing OpenDocument Extended documents. This mail is mainly to bring you awareness of the difference between OpenDocument documents and OpenDocument Extended documents that is written in the 854 pages of the ODF 1.2 part 1 specifcation.
