developing a data warehouse from parsed XML

My purpose is to develop a data warehouse, for which i downloaded an XML file from dblp (computer science bibliography website). I then parsed that XML file using the SAX XML parser.

After parsing i now have the following entities (Closing tags aren't printed intentionally):

  <dblp>
    <www mdate key>
      <author>
      <title>
      <url>
      <year>
    <inproceedings mdate key>
      <author>
      <title>
      <month>
      <year>
      <pages>
      <booktitle>
      <url>
      <note>
      <cdrom>
    <article mdate key>
      <author>
      <author>
      <title>
      <journal>
      <volume>
      <month>
      <year>
    <book mdate key>
      <author>
      <title>
      <year>
      <publisher>
      <isbn>
      <url>
    <incollection mdate key publtype>
      <author>
      <author>
      <author>
      <title>
      <year>
      <booktitle>
      <ee>
      <crossref>
      <url>
    <proceedings mdate key>
      <editor>
      <editor>
      <editor>
      <title>
      <booktitle>
      <volume>
      <series href>
      <year>
      <isbn>
      <publisher>
      <url>

According to mu knowledge the next step now is to develop a dimensional model (star schema) out of these entities, but i don't understand how exactly i have to do this with this much data. (Note: Its my first data warehouse project)

Is this data enough? What are the things i have to take care of?

What should i do next?
