about annotations in ebooks/pdfs:
what do you think would be the best place to integrate that?
there's one option of integrating annotations into evince (option 1) and
one option of integrating that into the read activity itself as a module
(option 2). are there more?
as we want to exchange annotations and comments we need (for both
options) some standard format for doing so (preferably some xml flavor).
did you have something in mind already?
now about the options:
- larger community support because also the gnome folks want to do
something in this direction 
- possibly easier of integration of the annotations into the "work" (pdf
- solution gets locked in into evince
- evince also needs to get a "give me your/take these annotation data"
interface so that annotations can be exchanged
- one has to get into the evince development process
- possibly easier development -- as python could be used; e.g. use
something like a SVG python rendering engine on a "glass layer" on top
of the actual "work" (pdf/ebook) to implement that; so that annotations
and comments can become independent of the "work" and can be shared
easily but maintain a spatial reference to the actual text they refer
to; SVG could then still be integrated into the PDF in one of its
metadata fields (needs to be tested).
-SVG could also serve as an exchange format directly
- have to implement some assurance mechanism that the annotations
actually apply to a certain manifestation of a work as once annotations
become rather independent from a manifestation of that work they tend to
live a life of their own.
- text highlighting becomes rather difficult as a spatial reference to
the line of text in the manifestation needs to be established, for which
one would have to interface with evince again.
please feel free to send your input on this. i also would like to put
this on some wiki or another. is there a good place for doing so? the
last input on this one: http://wiki.laptop.org/go/Read, has been given
some time ago.
thanks a lot!
