linkeddatahub-6.4.0

Migration

• ldh create container and ldh create item only create: they send If-None-Match: * and fail on an existing document instead of replacing it; scripts that re-run them pass --if-absent to accept the existing document (#505)
• A write may type a document only as def:Root, dh:Container or dh:Item, and must leave it with one of them; a write stating any other type on the document is refused with 422 (#498)

Added

• PATCH accepts a SPARQL Update request of several operations, executed in order and applied to the document together or not at all, and the INSERT DATA and DELETE DATA forms
• An object block shows an image value as an image, including external ones and those whose host refuses framing (#503)
• The graph store's answer to every request, its entity tags and Memento are formalised in Lean (formal/http/), with the ACL model built on it and conformance replayed by the HTTP tests (#499, #500)

Changed

• The proxy answers 406 for an external non-RDF body whose type the request does not accept, instead of passing it through as 200 (#503)

Fixed

• The assistant recognises a write reported with ?url alone, as an executor that applies a plan's writes after evaluating it reports one, and lists the document instead of drawing the report as a result, and an upload reported with ?url and ?sha1 likewise
• A chart drawn as a Table shows every variable its query selects, or every property its graph's resources carry, instead of only its category and series
• A chart drawn as a Table is as tall as its rows instead of 400px, and a bar chart grows with its bars so that every bar keeps its label
• A malformed ?accept=, such as an unencoded application/rdf+xml, is answered 400 instead of 500 (#504)

Security

• An authorization granted on a class other than the hierarchy classes can no longer reach a document, since a write cannot give the document that type (#498)
