Re: [xdi] RDF -> XDI

Title: Re: [xdi] RDF -> XDI

Yes, it is cool. And very needed for Higgins which uses both RDF and XDI interchangeably.

Markus, this is cool in the extreme. Examples like this go miles to explaining the topic of how XDI relates to RDF!

I am working on a slight update to the XDI RDF Model doc (this will be v13) to post this week so we can use it to discuss $ and $$ on this week's telecon.

Hi XDI TC,

I have built a small new feature into the "XDI Converter" application:

https://graceland.azigo.net/xdi-converter/XDIConverter

It is now possible to use "RDF" as an input format. This is very basic, and not everything is supported. Don't expect blank nodes or certain fancy RDF features to work properly (yet).

Azigo/Higgins needs this for an XDI-based application.

Here's a super quick RDF example:

<?xml version="1.0"?>

<rdf:RDF

xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

xmlns:cd="http://www.recshop.fake/cd#">

<rdf:Description

rdf:about="http://www.recshop.fake/cd/EmpireBurlesque">

  <cd:artist>Bob Dylan</cd:artist>

  <cd:country>USA</cd:country>

  <cd:company>Columbia</cd:company>

  <cd:price>10.90</cd:price>

  <cd:year>1985</cd:year>

</rdf:Description>

<rdf:Description

rdf:about="http://www.recshop.fake/cd/HideYourHeart">

  <cd:artist>Bonnie Tyler</cd:artist>

  <cd:country>UK</cd:country>

  <cd:company>CBS Records</cd:company>

  <cd:price>9.90</cd:price>

  <cd:year>1988</cd:year>

</rdf:Description>

</rdf:RDF>

And here's the same data converted to the X3 Simple format:

=(http://www.recshop.fake/cd/EmpireBurlesque)

    +(http://www.recshop.fake/cd#year)

        "1985"

    +(http://www.recshop.fake/cd#price)

        "10.90"

    +(http://www.recshop.fake/cd#company)

        "Columbia"

    +(http://www.recshop.fake/cd#country)

        "USA"

    +(http://www.recshop.fake/cd#artist)

        "Bob Dylan"

=(http://www.recshop.fake/cd/HideYourHeart)

    +(http://www.recshop.fake/cd#year)

        "1988"

    +(http://www.recshop.fake/cd#price)

        "9.90"

    +(http://www.recshop.fake/cd#company)

        "CBS Records"

    +(http://www.recshop.fake/cd#country)

        "UK"

    +(http://www.recshop.fake/cd#artist)

        "Bonnie Tyler"

A smarter converter would of course also convert RDF property URIs to XRIs from an XDI dictionary (e.g. +country, +artist, etc.), but as I said, it's very basic right now.
