12:05:42 <simonstey> HolgerK: I realized that some builds were failing for the node-expr documents (seems as if the HTML rules were made stricter)

12:06:15 <simonstey> topic: phase 2
12:06:30 <AndyS> meeting: Data Shapes Working Group teleconference
12:06:50 <simonstey> nicholascar: any reports on the TF reports?
12:07:17 <HolgerK> https://github.com/w3c/data-shapes/pull/777/changes
12:07:26 <simonstey> HolgerK: PR 777 (please approve; it fixes the pixel thingy and also some bugs in the turtle file)
12:08:51 <simonstey> ... another topic is about a new feature which is somewhat of a property pair constraint
12:09:05 <simonstey> ... values of one property must be a subset of the values of another property
12:09:15 <simonstey> ... kinda like subpropertyof
12:09:42 <simonstey> q+
12:09:56 <nicholascar> ack simonstey
12:10:56 <simonstey> ... it's subsetequal
12:11:37 <simonstey> ... sparql part is basically dormant currently
12:11:58 <HolgerK> https://github.com/w3c/data-shapes/issues/786
12:11:59 <simonstey> nicholascar: TF profiling had a meeting 1 1/2 weeks ago
12:12:44 <simonstey> ... we added use cases and set a timeline for the completion of the document in a month and a half from now.
12:12:58 <simonstey> ... 7 use cases were submitted over time
12:13:50 <simonstey> ... there were 2 sections added, one is about: if you do validation and validate your data graph against a data graph
12:13:59 <HolgerK> q+
12:14:03 <edmond> edmond has joined #data-shapes
12:14:13 <simonstey> ... if you want to indicate that your data graph conforms to a specific shapes graph
12:14:18 <simonstey> ... how do you do that?
12:14:48 <simonstey> ... so we defined that
12:14:58 <simonstey> ... we are meeting again this thursday
12:15:30 <simonstey> mgberg: no additional topics, but andy brought up the possib
12:15:36 <nicholascar> ack q

12:15:44 <HolgerK> https://www.w3.org/TR/shacl12-core/#explicit-shape-target
12:15:51 <simonstey> ... possibility of the interaction between profiles and rules
12:16:15 <HolgerK> https://www.w3.org/TR/shacl12-core/#sh-shapes-graph
12:16:16 <simonstey> HolgerK: just wanted to mention sh:shape, sh:shapesGraph
12:16:57 <simonstey> ... both can be used to link shapes and data graphs in one form or the other
12:17:20 <HolgerK> ack me
12:17:35 <simonstey> nicholascar: yeah I was looking at that definition today when I was writing a little section there
12:18:29 <nicholascar> ack AndyS
12:19:31 <simonstey> ... basically conventions for claiming and recording that data has been validated against SHACL shapes, so systems don't need to repeatedly revalidate data that's already been checked.
12:19:38 <AndyS> ack me
12:19:56 <simonstey> ... created a profiling mechanism that establishes hierarchical relationships between validators -> if data is valid according to a specific profile, it's also valid according to broader standards it profiles. e.g. built validators for standards like DCAT and GeoSPARQL, where the GeoSPARQL validator was published by the same working group as the
12:19:56 <simonstey> spec itself, making it the authoritative validator for determining GeoSPARQL compliance.
12:20:31 <simonstey> AndyS: I'm wondering whether that's more of a workflow question rather than SHACL spec
12:22:18 <simonstey> edmond: we are triaging UI issues
12:22:37 <simonstey> ... categorizing them into two groups (high/low priority)
12:23:52 <simonstey> nicholascar: (for the previous part) creating a standardized way to persistently store validation results rather than re-running validations repeatedly. while validating data (like graphs) through workflows, we need a conventional mechanism to record which data chunks have passed validation without having to re-validate everything each time
12:24:22 <simonstey> ... e.g., if 10% of 1,000 graphs fail, they want to store the results for the 900 that passed rather than re-checking all 1,000. i.e. using profiling specifications to make claims about validated data objects by treating a package of SHACL shapes as a validator object that data can conform to, rather than just storing instantaneous validation
12:24:22 <simonstey> reports that lack persistent semantic meaning.
12:24:32 <simonstey> andy: update on rules document
12:25:26 <simonstey> simonstey: apologies for not reviewing PRs, will do better this week!
