Re: Hardf PHP library

Hello,

Congratulations on Hardf, it is great to have more choices for processing
RDF in PHP.

It is worth noting that EasyRDF was never intended to be handle large
numbers of triples. EasyRDF loads everything into memory, so the data
structures can be walked, queried and manipulated.


Could EasyRDf v. Hardf be linked to DOM v. SAX?
