GET /api/artifacts?query={"id" = [x,y,z]}

{
    collection: [
        ArtifactRepresentation
    ]
}

The return format is the same than GET /api/artifacts/:id/linked_artifacts (artifact representation)

It's not possible to retrieve more than 100 ids at once. moreover the size of the query is limited to the size of the URL the server can accept (4096 according to the RFC)

The collection returns artifacts that are readable by user given permissions (that is to say the returned collection can be lower than requested ids)

Warning: there are no ETAG nor "LastModified" headers to avoid refetch of not modified artifacts
