TG2- Storage of Annotations

[ArthurChapman]

Holger Dettki (Swedish Species Information) brought up the issue at TDWG2018 about how the annotations will be stored. With the data? or in an Annotation database to which the databases link. He suggested that this could work better with the "Annotations to Annotations" etc.

The current (internal only, constructed for ePANNDA) implementation in iDigBio is that annotations are stuffed in a db table along side the data tables in a PostgreSQL jsonb column. We will always have to have a local copy of any annotations for performance reasons whether we generated them or someone else did.

We're open to a global annotation store as a concept.

Discussion at TDWG2018 on how annotations may be returned and used by custodians and aggregators. We have the issue of users and others making annotations doing it following the same Annotation format. In addition - it essential that the annotations include a source. Without looking at it, I presume that is included.

@chicoreus @tucotuco @Tasilee @ymgan Is there anything here that needs to be mentioned in the documentation?

[ymgan]

Thanks @ArthurChapman ! I think it could helpful to be documented somewhere. We got the same question in the OBIS community and it was also asked during the panel session in TDWG conference last year.

I did got confuse a little whether this is something that the TDWG Annotations IG is working on and whether there is something concrete that people can already do. I remember @chicoreus mentioned about the use of W3C annotation data model about this.
