    Hi, I just tried a fresh bower install on the demo-site and it's loading one of the Wellcome PDFs without a problem.

    I experimented with using the 'cv' hash parameter to set the initial page, but ran into difficulties with it. I think it was a limitation of the pdf.js api, but not sure. Would be great to have some fresh eyes on it!

    I think the OCR/Alto stuff is probably beyond the scope of this gitter channel. Maybe try posting a question on the UV Google Group:

    https://groups.google.com/forum/#!forum/universalviewer

    I'll see if I can get @tomcrane to write an explanation.

    @edsilv: We're running Piwik and would like to have it count downloads through UV. Do you see any good solution to this?
    Edward Silverton
    @edsilv

    you can listen for this event in the containing page:

    https://github.com/UniversalViewer/examples/blob/master/examples.js#L358

    you should be able to use that to track using Piwik/Google Analytics etc

    if you try different types of download on http://universalviewer.io/examples/ you can see the events being logged in the console

    Do you think it'd be hard to add title to the selectedOption value (for search ordering) in the search angular app?
    I'm replacing the dropdown with some bootstrap dropdown links
    Edward Silverton
    @edsilv
    sorry, what is the search angular app?
    Øystein Blixhavn
    @blixhavn
    haha, wrong window :P Sorry

    hey @edsilv, is it possible to attach metadata to a single canvas? So that it updates on page change
    Edward Silverton
    @edsilv

    yep! this was added by the Riksarkivet:

    http://universalviewer.io/examples/?manifest=https%3A%2F%2Fiiif.riksarkivet.se%2Farkis!C0000263%2Fmanifest

    if you check the manifest you can see the metadata on each canvas

    @blixhavn
    cool, thanks :)

    @blixhavn
    Hm, it doesn't appear for me. Anything special I need to do to the config? I'm using the default one now.
    Here's my manifest: http://pastebin.com/64PJ8crZ

    @edsilv

    perhaps you're not using the latest version of the UV? have you tried that manifest by pasting it into the manifest input field here?

    @blixhavn
    I have 1.6.14, latest from bower
    Edward Silverton
    @edsilv
    yeah, you want 1.7.x
    Øystein Blixhavn
    @blixhavn
    hm ok. When is that coming to bower? :)
    Edward Silverton
    @edsilv
    It's complicated! There has been some discussion around this on the UV slack channel. We need to figure out a proper release cycle. Currently I'm doing fixes/new features for the Wellcome and British Libraries on the dev branch. We need to all sit down soon and decide what the next release is going to be. From then on I'd like to plan each new release this way. Until then I don't want to confuse people further by doing more unofficial releases without a changelog etc. Your best bet is probably to just clone the UV and build the dev branch for the time being

    @blixhavn
    Alright, thanks for the info :)

    @edsilv: To speed up the user experience, we want to try pre-caching the first couple of zoom levels in OpenSeadragon. Do you know the rules for these? Are the dimensions of these constant, or dependant on the size of the viewer?

    @blixhavn
    Also, what would be the bottlenecks for presenting 2-300 images/pages of a book through UV?
