I wanted to test a java library (vaadin.com) and decided to implement the data.lotro.com-API to make this more interesting.
So I contacted Duwis earlier this year and also got answers, but he seems to have less time (as nearly every developer
). Unfortunatelly there are no complete XML-schemas (xsd) available, so I implemented everything what I got from tests. Also the data behind the API is not complete, so some of the items a char wears can not be detected, the API often provides uncomplete data and (some) kinships migrated from former Codemasters-servers can not be accessed.
I did not know about the Lorebook-API so far, but as far as I can see one is able to get the same results from both APIs at least for items.
Feel free to check out what I did, I think I implemented everything the data.lotro.com-API is able to do:
