Looking at capturing provenance information about data processed by code running on AWS Lambda. Wondering whether to use prov:SoftwareAgent to represent the function or a specific execution environment. Ideas welcome!

I'm using a versioned S3 bucket to store the documents, so can either have each patch with a distinct object key, or use the same key for all patches to same resource and stack up the patches as versions of that object... choices 🤔

I've got some RDF Patch documents describing changes to some resource over time. If I want to make those patches available, should each patch document get a distinct URL, and/or are those different states of the same (abstract) patch resource?

2) Construct/insert statements with the constraint baked in and then do path across those statements: construct { ?s ex:knowsFemale ?o } where { ?s schema:knows ?o . ?o schema:gender schema:Female . }

1) Enumerate all possible path lengths with the constraint expressed in the graph pattern: select * where { { ?s schema:knows ?o } union {?s schema:knows [ schema:gender schema:Female ; schema:knows ?o ] } # extend as needed ?o schema:gender schema:Female . }

My initial impression is that it is not possible to express as a property path. A couple of possible approaches are:

In SPARQL is it possible to enforce constraints on nodes traversed in a arbitrary-length property path? For example, I want to find schema:knows+ with the constraint that all nodes along the path have schema:gender schema:Female

Found this example that uses "lame" repeat polling. It might be a basis, but it would be good to have some back off mechanism for long-running imports.

i.e. enter a wait state until the bulk load completes and then continue to a next state depending on if the import succeeded or failed.

Does anyone using #Amazon #Neptune have a good way to monitor bulk load jobs, other that repeat polling of the Get-Status API? I'm looking for something that is event driven and can be easily integrated into a Step Functions workflow. @oralassila

Doing random stuff in XSLT used to be a hard, but I see there is now a random-number-generator function 👀

Hey #javascript #node tweeps, seems the Fetch API automagically inflates a gzip encoded response body, is there a way to grab the original response stream?

Have Microsoft co-opted the term Semantic Model? Do I need to start talking about ontologies instead? https://t.co/4K7TwC0SiK
