Categories has cycle

Postby dido » Tue Jun 14, 2011 3:15 pm

Dear Sir,

In readme.txt file categories is described as a DAG (direct acyclic graph) but I noticed 2 cycle:

#id,name,parent_id
256,'Systems Biology',257
257,'Computational Systems Biology',256

and

#id,name,parent_id
28,'Network Analysis',55
55,'Graph Theory',28

Dear contestant

You are correct, the category data from Vl.net site are not DAG .
For example one cycle:
http://videolectures.net/Top/Computer_S ... s_Biology/
and
http://videolectures.net/Top/Biology/Systems_Biology/

 We will put this in news on site. 

thanks,
Best regards,
Organizers
