I have one more question if that’s ok – do you have documentation/notes for any of the other tables that exist in the lrcat file ? or specifically those related to publishing to flickr

The reason i’m wondering is i’m hoping to manually fix a mismatch between my lightroom flickr files and the ones that are already at my flickr account before i got lightroom

I’ve tried your flickr plugin but for whatever reason(i think it’s caused by lots of braketed HDR shots) it won’t match up the local and flickr files

Mark

No, sorry, I haven’t looked at the DB schema in years. —Jeffrey

Great plugin by the way

One question – i was looking at the tables defined in lrcat files and notice almost all of them are prefixed by Ag – any idea what that stands for ? just curious

“Ag” is the chemical symbol for silver, an important component in the history of photographic film development. —Jeffrey

Yes, well I was dreaming about it last night, and I realized that the only real way to do what I wanted would be to use a supplementary database for the modifications I was considering. Thanks for the tip on the manager! Ah.

Thanks for the tip on the manager!

Thanks for the information! I am writing a CakePHP application that would DEFINITELY benifit from having direct access to the Lightroom database. The question now is how these tables are all related to one another. I did not see any FK declarations in there. I suppose I could just go and open my own database and poke around... :-/ Writing to the database would be a real kicker too. I take it the database is effectively LOCKED if Lightroom is running? So running a php app concurrently with Lightroom would fail? Again, I suppose I could experiment myself. Don't tell. :-D <span class='jfriedl'>The data in this post is very, very old. You can use the <a href='https://addons.mozilla.org/en-US/firefox/addon/5817/' rel="nofollow">SQLite Manager plugin for Firefox</a> to look around in a catalog, but it's very complex, and if you try to update anything you run a very real risk of destroying the catalog. Not recommended. I found it interesting to look at years ago, but I never touch it now. —Jeffrey</span> This is brilliant. Thanks for the information!

At my photography school, the teacher is always asking what we have done to our images since importing, and it would be nice to not have to create a develop status list by hand for each one.

I've been plenty happy with DBD::SQLite2 for the past few months, as it gives me that sort of instant database I often find I want in my apps without most of the hassles of having to deal with an "actual" database.
