Android Intent Database

Is there an Intent-database where one 开发者_如何学JAVAcan search for applications that publish common services? For example I could have an idea about a filter that could be applyed to photos in a photo-application, but under what intent should I publish my filter so that other applications can find it and use it?

So the question is if there are a more or less standard database for intents and when to use them? And then I don't only mean the android intents, although a list of them would be nice too :-)

Thanks in advance Roland

Yes. OpenIntents is one registry and the google apps have their own listing.
