Tables
As of SMW version 1.7:
- /smw_atts2: relationships where the value is numerically/logically significant, or a "string" (non-page type)
- /smw_conc2: not sure; probably concepts
- /smw_conccache: not sure; presumably a cache for concepts
- /smw_ids: assigns IDs to all properties, and values that map to a (potential) wiki page
- /smw_inst2: not sure
- /smw_redi2: not sure; redirects?
- /smw_rels2: relationships where the value refers to a (potential) wiki page
- /smw_spec2: URLs to SWiVT specs
- /smw_subp2: not sure; sub-property map?
- /smw_subs2: not sure; looks like a mapping of categories to sub-categories
- /smw_text2: relationships where the value is a long text/data blob
Core tables are boldfaced; the others seem to be primarily for optimization or auxiliary purposes.
Explanations
- Semantic relationships are defined in /smw rels2, /smw_text2, and /smw_atts2.
- Correspondence between SMW entities (property names and some property values) and MediaWiki pages is defined in /smw_ids
- Presumably the type of storage can be determined by looking up the SMW ID in /smw_spec2, making it unnecessary to check multiple tables (rels2, text2, atts2) for each property. but it does not seem to have been designed for this purpose.
