Blogger API, posting a message (with tags)

Here's some code from the current version:

Data = entry_new("Test no1", {"tonio", "ako@gmail.com"}, <<"TestContent">>, ["erlang", "test"]),
request(Auth, iolist_to_binary(Data)).

• The Title,
  
• The author, a tuple with authorName and authorEmail
• A binary holding the content of the post
• A list of tags

I think I'm on the right track...
