Systems selections

This article is for choosing good systems (technical) for The Consumerium Effort - Enhancing Consumer Informedness

Factors affecting systems selections

Copyleft 'free to modify' and 'free of cost' software is strongly preferred over other solutions.
Minimal modifications made (MMM) is an preference as well. This will ensure that we don't get swamped down on patching ad-hoccy, unstandard aged solutions to keep 'em working with the new stuff.

Integers w:BASE10 for integers, size depends on available solutions. Escape integer ceiling by bluntly encoding the integer as string of BASE-10 chars, dirty hack but could do the trick.
Condense URL encoding w:BASE64 and 64 possible characters, exactly 6 bits from w:ISO/IEC 646 (hard compatible with 7-bit ASCII)
w:UTF-8 encoded w:Unicode for text. UTF-8 is efficient and allows 2^32 different characters.. unless escaped to 40-bit in future revision

Programming languages

Main article: Databases

Currently using all major free software RDBMS:

Considered databases

Graph databases and Subject-predicate-object databases seem to perform the same thing just with different architecture and suitability for certain searches. See Talk:Databases for more on this.

Candidates for testing

Frameworks for glueing into various systems

Semantic MediaWiki compatibilities: PHP, Semantic Forms, enter data in wiki code -> RDF <-> Graph -> Outputs wikirenders and public SPARQL endpoints

...

APIs to communicate with:

Semantic MediaWiki well thought out and set up on implementation wiki (c.consumerium.org)
Development Wiki - User database, userspace sharing or importing and Unified Login are being looked at as options.

DBpedia Public SPARQL endpoint of DBpedia.org and Projects and efforts using DBpedia are very relevant.
Wikidata Public SPARQL endpoint of Wikidata.org (Wikidata Query Service)
