Two labs. Tasks/materials given at the second lecture.
Two labs on the same theme.
 
=== First lab ===
 
Date: 13 February.
 
Implement a system which can read html annotated according to the RDFa standard.
The data read should be saved and printed in several formats:
* csv
* rdf xml syntax
 
You will have to either find suitable annotated html pages or annotate some existing pages yourself (at least three pages).
 
Additional reading:
* [[Media:portaalidekoosvoime.ppt]] või pdf kujul [[Media:portaalidekoosvoime.pdf]]  (Estonian)
* http://www.w3.org/TR/xhtml-rdfa-primer/ või uuem  http://www.w3.org/2006/07/SWD/RDFa/primer/
* http://www.w3.org/2006/07/SWD/RDFa/syntax/
 
You may also look at some practical non-obligatory programming suggestions in Estonian: [[rdfa esimese praksi soovitusi]].
 
=== Second lab ===
 
Using the results of first lab for rule-based derivation of new information. Details will be given in the beginning of March.
