[Sigia-l] IA=webmaster?

[Ì·éÅ TAN Rong]

Dear members,
  I'm a librarian in China, and I was majored in Computer Sciences for bachelor
and master.  Due to some reasons, I left the software engineering occasion
business.  But I still would like to find related jobs to do.  Now I'm looking for
an area related to both my former major of computer sciences and my current job of
librarian.  And I noticed the "IA" area of study.
  Since I subscribed to this list, I've seen quite some postings providing job
positions for webmasters or web designers.  Then I asked my former roommate in
college still doing software developer job.  His reply gave me an insight to the
IA concept: "For example they don't need to know how to program, but they need to
know what a product can do and what a product can not do, what are the popular
products for solving a specific problem, what is the industry trend, the advantage
and disadvantage of a solution."
  Can anybody give me some more professional idea?  Thanks a lot!
Yours, sincerely,
Rong Tan
