Anonymous Nodes for SASSY
The anonymous nodes have now been implemented and tested.
The core part was doing a Base64 encoding of the 16 byte UUID. There are many implementations of this floating about, so, obviously I had to invent my own. The thought was that there isn't any functions in standard libraries that can copy a single bit from one object to another. Time there was.
Two alternative designs were examined. One uses a mask to select the bit and another to set it in the destination. The other shifts the bits from and to the desired position. The latter requires no branches, so I thought it might be quicker, but it was actually about 10% slower.
The end result was a little slower than other solutions for Base64 encoding that process multiple bits at once. However, I do think this version is a lot clearer about what is being done.
Now I just have to examine each of the 100 or so places that use blank nodes and see what changes to make.
The definition of insanity is attempting the same thing twice and expecting different results.
So I’m about to embark on building a #csvw and #rdf qb service for cube data. This time it’s a RESTful API with some #OGC querying patterns baked in.
For the second time. The previous attempt was csvcubed. It because we asked people to write json to have it write more json.
LintedData is a linter for RDF and Ontologies for easy use in CI pipelines, we recently released. It checks for common violations of best practices in ontology engineering.

Docker: https://hub.docker.com/r/dlrdw/linteddata/
Today I present LintedData at the Helmholtz Metadata Conference 2026 demo session.

The linked data viewer / dereferencer LDView can now be used without an expensive SPARQL endpoint.
Just convert your RDF data to the hdt format and use that as a datasource. You can even SPARQL them using the integrated Yasgui interface.
Above all, LDView attempts to offer a human friendly interface for providing RDF data.
Linked data viewer / resolver LDView has improved display of blank nodes / skolems and inverse relations.
Dear @timbl,
I kindly ask you to consider talking to the people at #Mozilla to keep #xml documents with human-friendly rendering via #xslt visible in #Firefox.
Not only needs the web decentralisation, but also raw, machine-readable data in human-friendly appearance. #Feeds, #RDF, etc. Dropping #w3c standards and backwards-compatibiity in this regard makes the web an unreliable medium for long-term publishing and archiving of such documents, even more so for small entities with limited resources. Big players have no problem continuously overhauling their archives to meet the viewers' habits du-jour and adapt to fast-moving, volatile practices.
Please say no to this #enshittification.
Yours,
@mro
