TMQL tutorial, part 3

Published by {{by}} on {{at}} and updated at {{updated}}.

Abstract:

This is the third part in a series of TMQL tutorials.

Learn with this series of TMQL tutorials how to query Topic Maps with a structured query language. With Maiana you can exercise all examples given in the slides (you have to be logged in to query maps in Maiana). The TMQL4J library allows you to use TMQL in all of your applications and provides you a detailed documentation of all TMQL features.

Part 3 of 8 of the TMQL tutorial covers postfix filters and projection. (If that isn’t meaningful now, it will be at the end of this part of tutorial.) Operators in TMQL are also covered. (All slides are in German.)

Go back to part 2 of this TMQL tutorial.
Proceed with part 4 of this TMQL tutorial.

As a former information scientist, I am fascinated since 1999 by the capabilities for building Topic Maps-based knowledge systems having the potential to augment human mind. One can model arbitrary knowledge organization systems, deal with semantic heterogeneity, collocate all facts about one subject in one logical place, and with TMQL have semantic retrieval on federated semantic networks. Therefore I expect bright prospects for business concepts building on the exchange of such knowledge snippets via semantic knowledge services.
