About

Usage

Generally, Topics are to be used in the following places:

  • Topic pages (show what titles are assigned)
  • Topic index (show what item types are [(1) available (2) in stock] for each topic)
  • Title pages
    • show what topics the title is in
    • summarize how many other titles are available for each topic
    • (future) show thumbnails for titles in topics with the A flag

In most display context, Topics should be sorted properly. (I thought I had already documented this but can't find it anywhere, so this is a first-pass reconstruction.) Sorting should generally be:<mysql>ORDER BY Sort, Name</mysql>

History

  • 2010-10-13 Coding (store and admin) in progress; noted 3 possible fields to add
  • 2011-02-04 working
  • 2011-02-05 New fields: NameMeta and Usage
  • 2011-02-24 New fields: cntTiHere and cntTiSub to support lookup-free indication of where to find active titles
  • 2011-09-28 renamed from brs_topics to cat_topic

Future

  • Fields I'm considering adding:
    • A) a flag to indicate that thumbnails of other items in the same category should be shown
    • B) a prefix to be added to NameFull for all child nodes (and maybe a flag to override it)
    • C) a way of creating "virtual" nodes to cross-link to related topics in other branches

SQL

<mysql>DROP TABLE IF EXISTS `cat_topic`; CREATE TABLE `cat_topic` ( 

 `ID`        INT              NOT NULL AUTO_INCREMENT,

 `Name`      VARCHAR(128)     NOT NULL COMMENT "generic name (context-free, but as short as possible)",
 `NameTree`  VARCHAR(64)  DEFAULT NULL COMMENT "name within context of parent; defaults to Name",
 `NameFull`  VARCHAR(255) DEFAULT NULL COMMENT "descriptive standalone name (context free, can be long)",

 `Usage`     VARCHAR(255) DEFAULT NULL COMMENT "usage instructions for this topic - show when editing topic",

 `Sort`      VARCHAR(15)  DEFAULT NULL COMMENT "optional sorting key",

 `Mispeled`  VARCHAR(255) DEFAULT NULL COMMENT "same as Variants, but these are WRONG spellings; avoid displaying",
