Working search prototype and a SWORD fight

November 23, 2010 3 comments

Since the last meeting, Mike has done a great job in putting together a working (search) prototype that uses the Xpert API to search http://www.nottingham.ac.uk/xpert/ for just those resources tagged “alpsportal” i.e. ALPS resources that I have added to our repository and that have been harvested by Xpert.  Currently Xpert is only harvesting Leeds Met but it should now be fairly straightforward to also harvest YSJ and Leeds such that any resources appropriately tagged will be returned from the portal.  It’s on a restricted test server at the moment so this what it looks like (with a few explanatory slides):

And the SWORD fight? There are 3 repositories (possibly 4 if we count JORUM) that we need to be able to deposit into – this is a problem as currently only one of them – intraLibrary at Leeds Met – has fully functioning SWORD.  This did lead us to consider a hybrid deposit process allowing for manual package forwarding but given limited technical resources (this approach would have its own, not inconsiderable, overheads) and the clear advantages of utilising SWORD, it probably makes sense to focus on a prototype that can utilise the protocol and that can, hopefully, plug into the other repositories in the future.

One of the issues we face is that intraLibrary is based on IEEE LOM and only accepts IMS Content Packages by SWORD whereas the majority of (open source) repositories are based on Dublin Core metadata and only accept METS by SWORD; I have been working with Jorum to test their SWORD deposit – as a customised DSpace repository it accepts METS (not IMS) so we have had to map IMSCP for one of our resources -> METS in order for it to be accepted.  Currently I have only been able to achieve this with a very simple package comprising just title, description and author (I’ve also tried to add keyword and rights but these don’t seem to be picked up by Jorum – I’m not sure if this is a problem with Jorum or with my XML – probably the latter!)

It is still a moot point whether we will need METS or IMSCP for YSJ/Leeds until various questions around their specific repository implementations have been answered but we probably need to progress on the basis that we should support both. We will need to get Mike involved on the technical side and I’m hoping that he can start developing a web-based SWORD deposit client that, eventually, will be able to post to any SWORD service URL whether at Leeds Met, Leeds, YSJ or Jorum; as the only viable target repository at this stage is Leeds Met we will want to package as IMSCP in the first instance, ultimately with a view to also packaging as METS depending on the requirements of the destination repository.

MT – I may be asking for the moon on a stick here but I know you’ll put me straight and tell me what we can actually achieve and in what time-scale…just to summarise, below, what (I think) I understand about SWORD so far and what I anticipate might be required of this type of implementation:

SWORD works by means of a service URL that a package is posted to via the ATOM publishing protocol – this service URL allows a “service document” to be retrieved from the target repository which itemises available collections for SWORD deposit. The desktop client I have been using with our repository and with Jorum is available from Sourceforge – http://sourceforge.net/projects/sword-app/.  It enables me to post a .zip containing a resource + its metadata in an imsmanifest.xml to intraLibrary (or resource + mets.xml to Jorum)

I imagine we would need a web-form that allows similar metadata to be captured and transformed into an imsmanifest.xml, then allows file upload and zips resource and manifest into an IMSCP that is then posted to a specified collection in the service doc at http://repository-intralibrary.leedsmet.ac.uk/IntraLibrary-Deposit/service.

Erm, sounds a bit tricky to me, Mike?

It might also be worth looking again at Stuart Lewis’ EasyDeposit (blogged about at http://repositorynews.wordpress.com/2010/06/04/easydeposit-the-sword-client-creation-toolkit/) which packages as METS for DSpace/EPrints etc.

ALPS resources

November 5, 2010 3 comments

The ACErep project, of course, is focussed on selective deposit into multiple repositories and cross-search of those repositories.  However, not having been involved in ALPS from the outset I feel a little ignorant of the precise nature of those resources.

As I understand it, one type of resource is an instructional video that can be accessed from a mobile device in a Practice Setting and there are a series of such videos in LUDOS and DigiRep.  Our repository at Leeds Met, however, has been conspicuously lacking any ALPS resources so I thought I’d do some experimentation with one of these resources to see how they behave in the respective repositories when accessed from both a mobile device and a desktop browser. (presumably these issues were considered as part of the main ALPS project?)

The video I chose is called “Measuring Seat Height” and can be found in LUDOS and DigiRep but I couldn’t figure out how to link to it in either system and just get a “Session expired” pop-up in DigiRep and “You have not performed a search” in LUDOS – find it by browsing from http://ludos.leeds.ac.uk/ludos/ and  http://www.yorksj.ac.uk/library/resources/archive/index.aspx

In LUDOS, the resource includes a URI that – in a desktop browser – opens a separate window that plays the .flv and also includes two links to download the .flv OR a .3GP (for a mobile device)

I downloaded both the .flv and the .3GP and uploaded them both to the Leeds Met repository:

http://repository.leedsmet.ac.uk/main/view_record.php?identifier=3726&SearchGroup=Open+Educational+Resources

http://repository.leedsmet.ac.uk/main/view_record.php?identifier=3725&SearchGroup=Open+Educational+Resources

In addition I uploaded them to JorumOpen:

http://open.jorum.ac.uk/xmlui/handle/123456789/11305

Incidentally, good old Xpert harvested us overnight so the .flv is available from there too (not yet the .3GP as I only uploaded it this morning – 05/11/10):

http://www.nottingham.ac.uk/xpert/scoreresults.php?advancedwords=%22seat+height%22&contributor=All&creator=All&format=All&language=All&publisher=All

A desktop browser cannot play a .flv so would need some sort of player to display from http://repository.leedsmet.ac.uk/ – presumably both LUDOS (DigiTool) and DigiRep (ArchivalWare) include such a player as the video does play in both those systems; intraLibrary, however, does not appear to include such a facility and FireFox and IE gave me the option to save or open with QuickTime (Chrome just downloaded it); the .3GP did play in browser (FF and IE – again Chrome just downloaded it) but when I tried the .3GP on my iPod it tried to play but then I just got an error message saying “Server not Configured Correctly” – I tried it this morning on @DebbieMN‘s iPhone with a similar result except Safari seems to have got stuck in a loop that we can’t now stop! (I did post the link to Twitter so I hope I haven’t broken anyone else’s phone!)

@Unicycle_OER suggested that iPhone/iPod will need the new vlc player from the app store to play a .3GP so I’ll try that later on my own device.

ALPS used an alternative mobile device to Apple i-stuff i think so I’ll have to get hold of one to test further…
