HTML header metadata

At least author, title and description shall be there.

Test with e.g. zotero connector plugin.

We have to decide which metadata may be interesting. we may get hold of the edition&work metadata, the path and the project description and name.

Here an example what metadata we can get hold of for an eltec object:

• edition & work & self metadata
• project metadata

So we may provide:

• title - from metadata
• author (agent) - from editon&work
• description - from path? from project description?
• keywords - from editon&work subject or rdf?
• handle pid - from metadata

also to discuss for which objects we want to hand out this metadata

• TEI
• Images
• Aggregations
• plain text / markdown
• ...
