Re: [Dspace-tech] HTML5 and the future of DSpace // Proof of concept for video tag in XMLUI
Mark, I had a few minutes today, so I worked up a proof of concept based on what you suggested. It works pretty well. It would have to be adjusted to account for browser support and the like. Still, you were right. It works. I posted directions for implementing it on the wiki. http://wiki.dspace.org/index.php/Add_HTML5_pseudo_streaming_%28Manakin%29 Jason Fowler, CA, MSLS Archives and Special Collections Librarian The Southern Baptist Theological Seminary jfow...@sbts.edu From: Mark Diggory [mdigg...@atmire.com] Sent: Friday, October 30, 2009 7:41 PM To: Mr Havercamp Cc: DSpace-tech@lists.sourceforge.net Subject: Re: [Dspace-tech] HTML5 and the future of DSpace For DSpace XMLUI, this is simply a matter of creating an appropriate theme that will support HTML5 as the output format for generated html content.

Re: [Dspace-tech] HTML5 and the future of DSpace
In Mark Wood's last message, he stated that We need to examine the different codec bundles provided by the browsers that implement these elements at all. (Do we provide multiple encodings, or point to add-on codec packages, or some of each, or...?) This stuff will affect and be affected by our sites' acceptable-formats policies. I think the point about multiple encodings is especially important to discuss. At this point that both Firefox 3.5 and Google Chrome support the Theora codec natively, but no one knows what Opera, Apple, and Microsoft will eventually do with their browsers. One current framework that's helping extend the use of the video tag is Video for Everybody! (http://camendesign.com/code/video_for_everybody). The usability approach taken by the framework's programmers relies on having two bitstreams, one created using the patent-encumbered H.264 codec, and another created using the open video codec, theora. On a side note, use of the H.264 codec could become really pricey by 2011, when the MPEG LA begins enforcing licensing fees. Personally, I hate the idea of having multiple encodings for accessibility purposes, primarily because video is already a space hog. But I also think we need to save the time of the reader (in this case, watcher), and if multiple encodings can help that cause, it's worth considering.

This would be an excellent project for those in the community who are working on DSpace Manakin XMLUI themes to provide as a contribution and would be most exclusively an exercise in XSLT. Well, there are various aspects of HTML5 that I think we need to consider separately. There are new elements we can use to mark portions of the page as headers or footers or sidebars or the like. They don't greatly affect the experience of most users, at least not right away, and it doesn't greatly matter to most users if they don't yet have browsers that can understand those elements. We can start working out appropriate uses of them and using them without much worry. Yes, let's begin taking advantage of more-meaningful markup and let the benefits be realized as the client tools fill in. HTML5 attempts to give less of the sort of room for interpretation that has resulted in the worst cross-browser compatibility horrors of previous versions. We will need to pay attention to such matters, to avoid surprising or inconveniencing the user of a more strictly compliant browser. Other elements bear still more scrutiny. There is a long-felt need for better support of audio and video material, and the new audio and video elements might be used to meet that need. But here the user's browser makes the difference between it works and it fails, and perhaps chides you for not upgrading daily. We also need to understand the performance characteristics of embedded media vs. streaming vs. magic Flash widgets. We need to think just a bit about how we count downloads of something that could be started and/or stopped in the middle. We need to examine the different codec bundles provided by the browsers that implement these elements at all.
