About
- Purpose: Stores data for images relevant to displaying catalog entities (currently only Titles)
- History:
- 2010-11-15
- Added ID_Folder to allow use of different base URLs via Template:Vbzcart.
- Removed WebSpec because nothing was using it and some of the data was missing and all of it used DOS-style paths.
- 2010-11-16 Added WhenAdded and WhenEdited fields because... well, it's easy to do, and provides a secondary check against the event log.
- 2010-11-15
- Fields:
- Spec can either be the official location of the file or can be updated from FileFerret using the IDFF data. It should eventually be renamed to something like LocalSpec, StorSpec, SrcSpec...
- WebSpec should be considered the official location for the purposes of page display; only image admin functions should update it.
- FileFerret columns:
- IDFF_File should always be set; this way, the file can be located if it gets moved. NOT NULL isn't required, though, because it may be necessary to find the file first and later request a FileFerret ID for it.
- IDFF_Fideal is set opportunistically, for now. Later on we may want to have a policy that all VbzCart images should have a Fideal, but this will be determined as FileFerret is worked out.
- Future: I had boldly planned to use FileFerret to manage image files, and towards that end had boldly removed any actual filespec information from this table, but then later realized that this was placing too much tight dependency on another entire subsystem. Maybe FileFerret should be responsible for keeping track of apps that use it, and for notifying them if any of their files are moved.
