Tools are scattered

How to find them? Which to use?
Every team wastes time going through a similar research and
selection process.

IDEA: LAMP for RDF

Create a bundled release of RDF tools, analogous
to a standard LAMP stack, or Red Hat or Ubuntu; so that if
someone wants to use RDF all they have to do is install that
bundle and they're ready to go.

Richard Cyganiak called this the "LARP" stack:

"such a platform already exists :) We call it LinkedDataHub":

IDEA: semantic web generic client in a box

"Simply start a server pointing at a SPARQL endpoint(s). Optionally
configure it with some example queries, metadata about what property to
derive labels (or introspect this from the endpoint itself), and get:

• A form interface for SPARQL queries with a menu of example queries
  that give you an idea of how to get started, plus some useful standard
  prefixes
• Simple linked data browsing (using conneg for html vs turtle)
• Dumb generic graphical browsing, a la neo4j
• Basic schema derivation; or just stats on most used classes and
  properties
• A generic semantic hypermedia API
• An autogenerated domain-specific swagger API (e.g. using garlik)"

You lost the target audience with "Simply ... SPARQL endpoint". In other words, the first sentence.

Might consider producing a family of https://yeoman.io generators.

btw, regarding "best" - the awesome list concepts growing on GitHub over the years seems useful. I'm contributing to https://github.com/semantalytics/awesome-semantic-web for that reason.

I've taken a crack at starting a list of software that might become a bundled LAMP-like release of software that a new RDF user would need to start building "typical" RDF applications:
https://github.com/w3c/EasierRDF/blob/master/RDF-LAMP.md

It's very meager so far. Anyone have suggestions for additions or changes?

Your single listed data store (Blazegraph) is no longer (for some years now!) supported nor maintained, as it has been subsumed into Amazon Neptune.

At the risk of blowing my (employer's) own horn, I would suggest Virtuoso Open Source be on the list, as it is the engine behind the majority of nodes in the LOD Cloud.

I would also nominate the OpenLink Structured Data Sniffer which helps reveal and/or confirm the structured data, in islands or markup or otherwise, found in any given web page. Several other of our browser extensions might also be well included.

I might also suggest retitling RDF-LAMP to Ramp or RDF-amp, because, to start with, Linux is not (always) part of your stack, given you've mandated that this stack run on Windows, macOS, and Linux. The other letters in that acronym (Apache, mySQL, and PHP/Perl/Python) also deserve demotion, as these are not the key ingredients of any RDF-based solution; an "amp[lifier]", howeer....

Ugh, thanks for catching that. I hadn't realized that they stopped supporting the open source version. That disqualifies it. :(

Sure, I'll list that at least for the moment. Thanks!

Would you consider that similar to the RDF Browser Firefox plug-in that Andreas Harth mentioned today on the semantic-web list?

I might also suggest retitling RDF-LAMP to Ramp or RDF-amp . . . .

I agree that it should be renamed, but I'd like to wait a bit to see how things evolve and see what other name ideas emerge, to avoid renaming it multiple times.

Fun fact: Virtuoso "Universal" Server came out some years after Apache. It is called Universal, because it is actually AMP, i.e. it has web server, relational database & triple store as well as Virtuoso PL, which is quite similar to PHP, syntax-wise.

The docu of Virtuoso is written for a professional audience, stuff like nginx, mariadb or mongodb or others are easy reads in comparison, maybe also because they can only do one thing and not many things. Also you can apt-get install it.

There's some similarity at a casual first glance, but I think there are significant differences.

First off, the RDF Browser plug-in is Firefox-only, while OSDS supports all major browsers including Chrome, Safari, Edge, Opera, and Firefox.

Second, I think relatedly, RDF Browser last pushed a new version in April 2021, and though there have been a couple of develop merges since, it appears to be rather stagnant. OSDS code maintenance hasn't been well disciplined, as a number of updated builds have shipped based on the develop branch without reaching the main branch, but that should be cleaned up shortly.

Third, and I think most significantly, the RDF Browser changes the HTTP Accept: header to include several extra media types, which may change the payload and/or media type of the server's response. In contrast, OSDS parses the "normal" payload returned to the browser, handling structured data found in POSH as well as islands (including entire documents) of Turtle, JSON, Microdata, RDFa, Atom, RSS, CSV, and others.

There are other differences, but I hope that's enough to entice you to install and explore a bit, and to add OSDS to the list.

To replace Blazegraph in Wikibase, Wikimedia developers recently did an evaluation of open source alternatives for Blazegraph.

I would propose to add OpenRefine + grefine-rdf-extension into the list for ontology population. Additionally, while it’s not mapped directly to one of the functionalities listed in the page, I would nominate YASGUI to be part of this RDF-LAMP
