	[Anton Güntsch (BGBM)]: Once we have completed our top (say) 500 collectors we would be very interested in organising a shared list of collectors with links to external ressources. For example, our list will have the HUH ID and also IDs to VIAF and WikiData. Meise could then easily retrieve VIAF and WikiData IDs using the HUH IDs.

			Several CETAF organisations have implemented IDs but not the redirection function. Others do have redirection but do not return RDF. This complies with the level 1/2/3 specification of CETAF URIs but should definitely harmonised. We should also continue to work on a prefered target (RDF) format (perhaps as a level 4).

			We also found that several implementations obviously did not map the new IDs in their GBIF provider software installations so that they are not visible on the GBIF portal. This should be fixed.

			Based on the assemssment of existing CETAF ID implementations, we investigated potential platforms for a central catalogue of CETAF IDs. Options would be a simple (mysql) database or some kind of advanced RDF triple store. A good compromise seems to be Blazegraph, which is a pretty easy to use and at the same time a capable triple store DB (https://www.blazegraph.com/).

			Our experiments with Blazegraph showed that harvesting from larges providers (e.g. RBGE with roughly 1M records) is working well.

			==== BGBM Results ====
			As a basis for semantic annotation of collectors and collector teams we exported 201685 specimen records from our local collection database (we have more records in JACQ, but wanted to start with something locally). We then extracted collector names from the table and imported them into an EXCEL file sorted by number of specimens mentioning the respective collector. We also added links to example specimens for each record.
			We then asked a student to go through the list and add links to collector pages in WikiData, HUH, VIAF. We also advised her to skip records if the mapping to a semantic resource seemed to be ambiguous or too difficult to find. Within one person week we achieved the following results:

			* 1082 collector names linked up to semantic resources (WikiData, HUH, or VIAF)
			* 71320 specimens where all collectors have been linked to a semantic resource
			* 63417 specimens with at least one collector linked to a semantic resource
