Going into the meeting

The plan is to look at sgv. Statements made are applicable to the archived version of sgv.

During the meeting

The one-file-one-resource flag does not need to be developed in the scope of the thesis since it’s an edge case. An alternative to the flag would be to create an ontology used by a derived container that contains links to the canonical containers.

It was pointed out that a SPARQL endpoint does not require an LDP container. What would be possible is to have an LDP server that is smarter than just being a file system mapping. This kind of server would have own reasoning allowing, for example, the sgo:state-requirements to be computed by the server.

When using the assume use case, the client enjoying relaxed client control should always provide an sgo description of newly created resources. Supplying this information should allow other applications to also find the resources.

When a power user, using the notification use case would use an application generating an sgo-notification, it could be nice to resolve it instantly. The user could be greeted with a user dialog where it should resolve the placement.

Different structured containers exist: links

An additional update condition could be an alternative to update-keep using a distance metric.

An alternative to the SPARQL group strategy would be the use of something used by TPF. Namely URI templates. Both can exist, the benefit of the sparql notation is that you have access to the world, while using URI templates combined with the shape description has an easier notation.

A sparql endpoint could be viewed as a canonical container, derived containers could be used to group multiple endpoints, or to get an LDP view over the container.

A name change of storage guidance ontology to storage guidance vocabulary was proposed.

Conclusions

What should be done now is:

  1. Apply the comments above
  2. Evaluate the vocabulary for LDP, LDES and SPARQL-endpoints. Might not go so smoothly.
  3. Decide what would be useful and feasible to implement in the context of a thesis.
