epubcheck error on svg file

[roger64]

Hi

It's a very basic svg file: just a plain backwards black arrow I made using Netscape. It triggers an EPUBCECK error (see screenshot) on line 17 (" <rdf:RDF>") that I do not understand. Somebody has a clue?

Spoiler:

ePubCheck doesn't like the RDF section, which isn't supported in ePub2 and ePub3. Just remove it.

Simply delete the namespace declaration:

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

and the whole metadata section:

  <metadata
     id="metadata7">
     <rdf:RDF>
      <cc:Work
         rdf:about="">
        <dc:format>image/svg+xml</dc:format>
        <dc:type
           rdf:resource="http://purl.org/dc/dcmitype/StillImage" />
        <dc:title></dc:title>
      </cc:Work>
    </rdf:RDF>
  </metadata>

Thank you very much. Indeed, that did the trick.
