Hey Andy,
I think we didn't discussed if empty segments should be included. In the
implementation I got I am not including those, I think is not necessary.
That's fine, it makes the implementation easier too.
I think the agreement was to report the error as an HTTP error, but that was
though more in the perspective of clients that are not supporting this
capability, trying to avoid servers responding paginated segments when the rows
attribute was not included.
Gustavo, do you mean segment= and nothing after the =? For features and
segment those are reported as an ERRRORSEGMENT for myDAS. We will keep
it in this way, right?

Absolutely, that's good.
I've updated the wiki with clarifications of these points, and an example
response illustrating how the server should choose which rows to return.
Cheers,
Gustavo.

Hi Gustavo,
Thanks for this, looks fine to me mostly.
One question: should segments that contain no features (due to the pagination
limit) be included in the response?
/das/foo/features?search=a*;rows=1-2
<GFF total="300">
<SEGMENT id="1" total="40">
<FEATURE id="a" />
<FEATURE id="b" />
</SEGMENT>
<SEGMENT id="2" total="30" />
<SEGMENT id="3" total="90" />
...
</GFF>
Also, I can't remember if we decided at the workshop whether servers would be allowed to overrule the
client's requested range and return (for example) a smaller number of rows. This is how entry_points works,
which is why it has "start" and "end" attributes in the response in addition to the
"total" attribute.

Hello all,
Following the momentum that the DAS workshop let us I started tackling one of
the many projects that we defined during the 3rd day: The pagination for the
features command.
I added the proposal for the extension in the wiki:
http://www.biodas.org/wiki/DAS1.6E#Pagination_for_DAS
I have implemented it in MyDas and is included in the snapshot version of the
repository in case anyone wants to play with it
http://mydas.googlecode.com/svn/snapshot-repository/uk/ac/ebi/mydas/mydas/1.6.5-SNAPSHOT/
As a nightly version it may have changes whenever we do a release after some
proper testing of it
Looking for your feedback about it!
Cheers,
Gustavo.
