These tips are mainly for installing applications that are not open source. For most of the open source applications, FC package manager, Yum will do the job.

  - If YES, prepends the brief description of a member or function before the detailed description.
• EXTRACT_ALL
  - If YES, all entities in the documentation are documented, even if no documentation was available.
  - Warnings about undocumented members will not be generated as long as this is set to YES.
• INPUT
  - List of directories containing source files.
  - If left blank, the current directory will be used.
• RECURSIVE
  - If YES, processes sub-directories recursively.

• XML and RDF (blog)
• Why RDF model is different from the XML model (link)
  - In XML, there are many ways to represent something like "The author of the page is Ora". In RDF, there is only one way.
  - While all the different ways may convey some meaning for the human reader, it will not be the case for a computer.
  - Querying in XML is more complex due to many ways of representing the same thing.
  - Mapping from XML to RDF is many-to-one.
• Using XML for Data (link)
  - An XML document can't have disjoint parts and therefore XML doesn't map 1-1 with a directed, labeled graph.
• Is RDF/XML Good for Anything? (link)
  - XML is designed to describe trees. RDF/XML is a transfer syntax for graphs.

• The Semantic Web and Entity-Relationship models
  - RDF is similar to E-R model except that relationships are first class objects in RDF.
  - In RDF, the set of slots of an object is not defined when the class of an object is defined.
• The Semantic Web and Relational Databases
  - In DB, a query can join tables by any comlumns which match by datatype.

 SPARQL Vs. RDQL

• From RDQL to SPARQL (blog) 

• Supports named graphs - query contains a FROM clause to specify the graph
• Supports queries with typed literals
• Sort results
