Greets, There are three issues in Lucy's JIRA which were filed a long time ago, and which remain on the wishlist/TODO-list, but for which there is no urgency:
https://issues.apache.org/jira/browse/LUCY-1 File Format Spec https://issues.apache.org/jira/browse/LUCY-3 File Format - VFS https://issues.apache.org/jira/browse/LUCY-4 Compound File Format Spec Right now, we provide a high-level introduction to the file format: http://svn.apache.org/repos/asf/incubator/lucy/trunk/perl/lib/Lucy/Docs/FileFormat.pod The envisioned spec would be more than that document, and more than Lucene's file format document: it would be a full-on spec from which conforming applications could realistically be implemented. In cleaning up Lucy's JIRA, Chris Mattmann scheduled those issues to be dealt with by release 0.1-incubating. If no one objects, I intend to move them back to unscheduled status (fix version == "unknown"). As an alternative, we might consider resolving them as wontfix, since I doubt they will get prioritized any time soon. Marvin Humphrey
