XQuery Working Group – Learn XQuery in the Company of Digital Humanists and Digital Scientists

From the webpage:

We meet from 3:00 to 4:30 p.m. on most Fridays in 800FA of the Central Library. Newcomers are always welcome! Check the schedule below for details about topics. Also see our Github repository for code samples. Contact Cliff Anderson with any questions or see the FAQs below.

Good thing we are all mindful of the distinction W3C XML Query Working Group and XQuery Working Group (Vanderbilt).

Otherwise, you might need a topic map to sort out casual references. ­čśë

Even if you can’t attend meetings in person, support this project by Cliff Anderson.

eXist: XQuery FLWOR Expression Updates

Friday, August 28th, 2015

Fixes for FLWOR expressions #763

From the webpage:

This is a major update to FLWOR processing in eXist to align it with the 3.0/3.1 specification. The “for”, “let”, “where”, “order by” and “group by” clauses are now implemented as separate classes (instead of being attached to a main “for” or “let”), and may thus appear in any place the spec allows. A FLWOR expression may have multiple “order by”, “group by” or “where” clauses. The previous implementation was too restrictive, allowing those clauses only in specific positions.

The “group by” clause, which was added back in 2007 and has been updated a few times since then, was completely rewritten and does now also support collations. The “allowing empty” spec within a “for” is now respected.

You need the nightly build version to benefit from these latest changes. (As of August 28, 2015. Eventually the changes will make it into a release candidate and then into a stable version.)

Currently available versions include:

Stable Release, version 2.2

Release Candidate, version 3.0 RC 1 (not recommended for production)

Nightly Builds, Use at your own risk

I first saw this in a tweet by Jonathan Robie.

eXist RC 1.4.1

eXist RC 1.4.1

I saw a post on a mailing list from Adam Retter with the following news:

I would just like to let you all know that the Release Candidate for eXist-db 1.4.1 is out, this is the culmination of two years of hard work. We take our releases very seriously!

eXist-db is all about XML, indexing and querying. We provide various indexes including full-text indexing of structured, semi-structured and un-structured content. Our unit of storage is the Document, XML or Binary. We can also extract and make searchable content from Binary Documents.

Not only is eXist-db an OpenSource XML Native Database, its also a fully fledged web application platform for XRX applications, so don’t let the ‘-db’ bit fool you.

Had not meant to be neglecting the XML databases. You are going to encounter them in a number of contexts, either as storing data you need or as repositories you address from within a topic map.
