/** |
18
|
|
|
* Class to access the SMW IDs table in SQLStore3. |
19
|
|
|
* Provides transparent in-memory caching facilities. |
20
|
|
|
* |
21
|
|
|
* Documentation for the SMW IDs table: This table is a dictionary that |
22
|
|
|
* assigns integer IDs to pages, properties, and other objects used by SMW. |
23
|
|
|
* All tables that refer to such objects store these IDs instead. If the ID |
24
|
|
|
* information is lost (e.g., table gets deleted), then the data stored in SMW |
25
|
|
|
* is no longer meaningful: all tables need to be dropped, recreated, and |
26
|
|
|
* refreshed to get back to a working database. |
27
|
|
|
* |
28
|
|
|
* The table has a column for storing interwiki prefixes, used to refer to |
29
|
|
|
* pages on external sites (like in MediaWiki). This column is also used to |
30
|
|
|
* mark some special objects in the table, using "interwiki prefixes" that |
31
|
|
|
* cannot occur in MediaWiki: |
32
|
|
|
* |
33
|
|
|
* - Rows with iw SMW_SQL3_SMWREDIIW are similar to normal entries for |
34
|
|
|
* (internal) wiki pages, but the iw indicates that the page is a redirect, the |
35
|
|
|
* (target of which should be sought using the smw_fpt_redi table. |
36
|
|
|
* |
37
|
|
|
* - The (unique) row with iw SMW_SQL3_SMWBORDERIW just marks the border |
38
|
|
|
* between predefined ids (rows that are reserved for hardcoded ids built into |
39
|
|
|
* SMW) and normal entries. It is no object, but makes sure that SQL's auto |
40
|
|
|
* increment counter is high enough to not add any objects before that marked |
41
|
|
|
* "border". |
42
|
|
|
* |
43
|
|
|
* @note Do not call the constructor of SMWDIWikiPage using data from the SMW |
44
|
|
|
* IDs table; use SMWDIHandlerWikiPage::dataItemFromDBKeys() instead. The table |
45
|
|
|
* does not always contain data as required wiki pages. Especially predefined |
46
|
|
|
* properties are represented by language-independent keys rather than proper |
47
|
|
|
* titles. SMWDIHandlerWikiPage takes care of this. |
