meaning of tags used in RDF dump

[Guest]

I'm trying to find information about meaning of tags used in RDF dump files. Actually, I would like to know detailed meanings (or differences) of <narrow>, <narrow1> and <narrow2> tags, for example.

 

Is a list of meaning of each tag available?

 

Thanks for your help.

well, there's some (but not quite what you want, I think) information at http://dmoz.org/rdf/ and http://dmoz.org/rdf.html .

 

To the best of my knowledge:

In the structure rdf, narrow tags show subcategories. (symbolic tags show @ links - categories located not directly underneath, but somewhere else, but *could* be logically considered subcategories of the current one)

narrow1, narrow2, and narrow [and same with symbolic1, symbolic2, and symbolic] show different "sort priorities" given to categories.

 

narrow2 is the highest, narrow1 is in the middle, and narrow is the bottom.

 

For example, see http://dmoz.org/Recreation/Theme_Parks/ and the following snipped from the rdf:

 

<Topic r:id="Top/Recreation/Theme_Parks">

<catid>218</catid>

<d:Title>Theme_Parks</d:Title>

<narrow1 r:resource="Top/Recreation/Theme_Parks/Disney"/>

<narrow1 r:resource="Top/Recreation/Theme_Parks/Defunct"/>

<narrow r:resource="Top/Recreation/Theme_Parks/Guides"/>

<narrow1 r:resource="Top/Recreation/Theme_Parks/Six_Flags"/>

<narrow1 r:resource="Top/Recreation/Theme_Parks/Attractions"/>

<narrow1 r:resource="Top/Recreation/Theme_Parks/Amusement_Centers"/>

<narrow1 r:resource="Top/Recreation/Theme_Parks/Legoland"/>

<narrow1 r:resource="Top/Recreation/Theme_Parks/Water_Parks"/>

<narrow2 r:resource="Top/Recreation/Theme_Parks/Individual_Parks"/>

<narrow1 r:resource="Top/Recreation/Theme_Parks/Paramount"/>

<symbolic1 r:resource="Zoos_and_Aquaria:Top/Science/Institutions/Zoos_and_Aquariums"/>

<symbolic r:resource="Equipment:Top/Business/Industries/Arts_and_Entertainment/Amusement/Equipment"/>

<symbolic r:resource="Consumer_Information:Top/Home/Consumer_Information/Sports_and_Recreation/Amusement_Parks"/>

<symbolic1 r:resource="Renaissance_Faires:Top/Recreation/Living_History/By_Region/Europe/Renaissance/Renaissance_Faires"/>

<symbolic r:resource="Manufacturers_and_Designers:Top/Business/Industries/Arts_and_Entertainment/Amusement"/>

<symbolic1 r:resource="Miniature_Golf:Top/Sports/Golf/Miniature_Golf/Courses"/>

<symbolic r:resource="Tickets:Top/Shopping/Entertainment/Tickets/Theme_Park"/>

A lot of the tags can be figured out by looking at where it happens and looking at the category at the dmoz.org site. .
