Wow, thanks for all the info! I researched paciolan recently and was pretty convinced they were running a closed system, thanks for confirming my suspicions. I also had a pretty good idea that TM was very restricted and inaccessable.

I'm trying to get access to ticket info in addition to venue info. Venue info I can easily get, but ticket info will be difficult. I've been researching how stubhub and other sites do it, but the only conclusion I can draw is that they have a financial agreement with TM to get access to their data, after all when you list a ticket on stubhub they need to verify the ticket ownership and validity (one would hope they do at least).

I was thinking of taking the yodlee approach by writing connectors that access dat through a series of API calls and simple HTML parsing, however there would probably legal implications to scraping TM sites, so no matter what, it would come back down to establishing an agreement with TM.

Any thoughts on this?
