Purge stale repository / graph

[ioggstream]

Comportamento atteso

• when a repository is not harvested, it should be removed

Comportamento attuale

• it lingers around

e.g.

select distinct ?g where {
GRAPH ?g 
} 

still returns a stale repository (e.g. https://github.com/ash1425/sample-ontology-repo and https://github.com/ronytw/sample-ontology-repo)

Notes

• we need to define an expiration policy for stale repositories
• we could publish the repository URL (e.g. the graph) together with the asset information
