Question

I may start working on a project very similar to Hipmunk.com, where it pulls the hotel cost information by calling different APIs (like expedia, orbitz, travelocity, hotels.com etc)

I did some research on this, but I am not able to find any unique hotel id or any field to match the hotels between several API’s. Anyone have experience on how can to compare the hotel from expedia with orbitz or travelcity etc?

Thanks

EDIT: Google also doing the same thing http://www.google.com/hotelfinder/

Answer 1

From what I have seen of GDS systems, and these API’s there is rarely a unique identifier between systems for e.g. hotels

Airports, airlines and countries have unique ISO identifiers: http://www.iso-code.com/airports.2.html

I would guess you are going to have to have your own internal mapping to identify and disambiguate the properties.
