I'm only so bothered in as much as i really don't want a desktop in the future to need 2 javascript engines and each application depending on 2 or 3 different database engines and so on :] you are indeed right, but I see couchdb can use different javascript libraries (it has a configure option to tell it where to find libjs) so I guess we could ask the couchdb guys to support our JS engine (when we decide which one to use :) ok, just asked the couchdb devels about this, and it seems to be much easier than I thought, so this should be easy to fix when we decide which JS engine to use. Indeed, one can use any language as a CouchDB indexer. Indexer - because that is really what the Javascript is used for. The (very) simplified explanation is that you can't do custom queries against Couch only index lookups, but you can create some very funky indexes. These indexes are generated by calling out to an outside process over a socket using some protocol defined in the Couch docs (which is also why Couch is still very fast, the script engine is only used on indexing time). This external indexer process use libmozjs by default but you can create your custom indexer in what ever language you want; Python, Perl, even C if you are adventurous. It should not be a big task to write an indexer based on libseed I think - although I haven't checked the details. no, shouldn't be a big task, as confirmed by the CouchDB developers this afternoon. The only thing that I'm not sure about is that they mentioned e4x (http://www.ecma-international.org/publications/standards/Ecma-357.htm ) being needed in the JS implementation, so does libseed support that?

Maybe I get this wrong but wouldn't it be easier to access CouchDB from libgda database-wrapper that we already have in the external dependencies? well, couchdb is not a relational database, in the sense that a CouchDB database (what could be treated in libgda as a table) can contain records with totally different fields, so it can't be easily mapped 1-1 to a relational table. For instance, for evolution-couchdb, we have a single database for contacts, but there's nothing preventing people from putting in that database records containing appointments, or notes, or whatever. We have though a special field for all records, called record_type (see http://www.freedesktop.org/wiki/Specifications/desktopcouch ) which specifies which type of record it is, so that could be used in libgda to, for instance, map a CouchDB database to a table containing all contacts. But again, what do you do with the other records, some of which might not contain the record_type field? Also, CouchDB offers some noSQL stuff, like adding attachments to JSON documents, and has the notion of conflicting documents which you need to resolve, so mapping that to a relational database might be a hard task. And also, the couchdb-glib API is straightforward (give me the list of dbs/documents, update this doc, etc), while making apps use libgda to access it would be a hard thing to convince maintainers (believe me I know, I've worked for many years in GNOME-DB, and tried to convince people to use it :-). This is not to say that libgda is not useful, of course it is, for applications accessing relational databases (or other formats easily mapped to relational databases). I like though the idea of writing a libgda CouchDB backend, but this could only be mapped to databases containing records with the record_type field, and with that record_type well documented. ___ desktop-devel-list mailing list desktop-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/desktop-devel-list

right, but local couchdb server can be on your home network, for

Need to get 20.2MB of archives. After unpacking 35.6MB will be used.
Do you want to continue? [Y/n/?]
CouchDB on Debian takes up 35MB of disk space. Not exactly lightweight.
right, this is because of lots of unneeded erlang dependencies. On
Ubuntu Karmic the dependencies have been reviewed (for inclusion on the
main CD), and I think it's just 14MB now (not sure about the exact
numbers, but can check if you want)

I talked with you about it, and haven't had time this cycle to look much at it, but yes, it might be interesting to look at using them, or at least integrating easily with tracker's usage of them I know the feeling. We should really sit down and look at this before your home grown ontologies are frozen, though. Will you or sil be at GNOME Boston? I'm not going, and seems sil is neither. But we probably could have some IRC meeting with the tracker, couchdb guys and anyone interested? ___ desktop-devel-list mailing list desktop-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/desktop-devel-list

Indeed, one can use any language as a CouchDB indexer. Indexer - because that is really what the Javascript is used for. The (very) simplified explanation is that you can't do custom queries against Couch only index lookups, but you can create some very funky indexes. These indexes are generated by calling out to an outside process over a socket using some protocol defined in the Couch docs (which is also why Couch is still very fast, the script engine is only used on indexing time). This external indexer process use libmozjs by default but you can create your custom indexer in what ever language you want; Python, Perl, even C if you are adventurous. It should not be a big task to write an indexer based on libseed I think - although I haven't checked the details. -- Cheers, Mikkel ___ desktop-devel-list mailing list desktop-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/desktop-devel-list

The only thing that I'm not sure about is that they mentioned e4x (http://www.ecma-international.org/publications/standards/Ecma-357.htm ) being needed in the JS implementation, so does libseed support that? ___ desktop-devel-list mailing list desktop-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/desktop-devel-list

No, JavaScriptCore (this is way out of libseed's jurisdiction) doesn't currently support E4X (only the Mozilla JS engine does, as far as I can gather from reading around).
