Hi Juraj,

yes, you need VisualWorks, but any old one will do, since it does not need any new stuff.

For a migration you need Values (simple, more below) and an XML implementation (I heard XML is robust in Pharo, but have not used it. The API may be different from the VW one).

The status of the implementation has not changed and I have just started to use it to implement XMP, which will change and refine the RDF API.

I am not aware of any other users. This means, that it is not speedified nor robustified 😊 – but any help is welcome!

Before last ESUG, I started to port RDF for the community, because someone asked me for it.

I started with the Values package by renaming my OrderedDictionary to Valuemap, because I couldn’t use the Pharo OrderedDictionary since it is kaputt. I am still suffering from this renaming, since it is at the core of all I do…

Later at ESUG, I had a discussion about porting with the one who asked me. Then I lost interest ☹.

So, if you want to do something, I can help you with any questions.

(But, unless there is a business case, I will not touch Pharo just for fun).

Happy hacking,
