This is the TripleDB, a way of persistently remembering "triples" of data.
|
|
|
|
Each entry is kind of a "subject-verb-object" set. For example, some
|
|
entries might be:
|
|
|
|
Noun Verb Object

This API is about storing, deleting, and querying such triples to a
|
|
database. Each member of a triple can be a string, integer, or date.
|
|
|
|
For more details, read the API, in tdbapi.h.
|
|
|
|
Note that TripleDB now depends on the Sleepycat Berkeley DB, version
|
|
3.1.11 or greater. For more information on that, see

FAQ:
|
|
|
|
Q: "Hey! There's no Makefile!"
|
|
A: Yeah, yeah, I know. This is developed as part of a project at
|
|
work, and our Makefiles are all messed up. If you have one that fits in well
|
|
with other stuff at mozilla.org, please feel free to contribute it.
|
|
|
|
Q: Um, so nobody else here uses this?
|
|
A: That's right. But this maps in pretty well to RDF, I believe. I wouldn't
|
|
be surprised if someone decides to use it to store a biggish RDF database,
|
|
and adds it to mozilla for that purpose.
