OMTD-Share metadata export

[antool]

The OMTD platform currently supports the addition of ontologies through the metadata records one-by-one. How to export the metadata of several ontologies?
AgroPortal team has identified several possibilities for handle this situation:

• A concatenation of the XML exports for all the ontologies (Disadvantage: the output is not valid XML as per the XSD spec.)
• A zip file containing one XML metadata export for each ontology (Disadvantage: There is probably nothing in to OpenMinTeD infrastructure to handle that)
• Only support exporting metadata on a per-ontology basis and provide a list of URLs in the deliverables for all the ontologies to be included in OpenMinTeD for each of the portals (Disadvantage: Not very elegant from a technical standpoint).

The OMTD team further discussed the issue and decided that the best solution is simply to register one metadata record for an ontology and then send a zip file with the metadata records for all the other ontologies (see https://groups.google.com/forum/#!forum/openminted-user-forum).
