This page collects some proposed service types and other suggestions as extension to the Document Availability Information API.

Additional Service types

Request

http://purl.org/NET/daia-ext/request

ILS 'request' function. Sadly, the typical ILS 'request' function can be used for a variety of actual services, including:

  • recall a checked out item
  • place a 'hold' on an item
  • request an item for delivery to a particular location (circ desk or other)

Where possible, you should not use the 'request' service, but should instead use a service expressing a more specific action availability. However, actually existing ILS's can make it very hard to figure out what more specific actions are available, and it may still be useful to advertise the ILS 'request' function, this service represents that.

Looks like a super-class of all service types with meaning "unknown". In this case we may better make the service field optional so if you can specify an unknown service. -- JakobVoss 02:12, 29 September 2009 (PDT)
That might work, as long as it's possible to specify a user-displayable label for the service. Won't be able to be understood/acted upon by software, but the user can still be told this is, say, a generic 'Request'.

Recall

http://purl.org/NET/daia-ext/recall

Recall a checked out item, which will typically then be placed on hold for you.

Placed for you for what purpose? -- JakobVoss 02:12, 29 September 2009 (PDT)
So are you suggesting this shouldn't be a service of it's own, but instead should just be indicated in the 'delay' and user-displayable comments on the actual end-purpose service, that a 'recall' is possible? One thing is that in my library I am told that the user wants to know if they will be recalling the item from someone else or not before making the request.
This should better be encoded in the 'delay' and 'queue' attributes. If I understand you right, you want to encode whether an item is hold by someone else or is not available for some other reason. If we start encoding this, we can build an ontology of reasons why I cannot get a book (someone else holds it, it's a the bookbinder, the cat of the librarian is sitton on it...) which is not purpose of core DAIA. Maybe you could add a custom 'reason' field to unavailable or an 'obstacle' field to available/unavailable. -- JakobVoss 01:39, 23 October 2009 (PDT)
Yes, I think I can buy this, seems workable, thanks for explaining. Jrochkind 19:27, 27 October 2009 (PDT)

Deliver

http://purl.org/NET/daia-ext/deliver

Request delivery of a physical item, to a circulation desk, an office, or even a home, depending on what the library provides.

Does deliver imply loan? I think a broad "deliver" does not help, but more specific services like "home-deliver", "office-deliver" etc. as subtypes of "loan". Delivering to a circulation desk is not a specific service in my opinion. -- JakobVoss 02:12, 29 September 2009 (PDT)
Why is delivering to a circulation desk not a specific service? I guess I'm trying to figure out how to represent the services that my library actually does offer. Now, I kind of see your vision of services, and I WISH my library offered the kind of services you're thinking of, and in such a way that my software could actually predict them... but it kind of doesn't. And I'm not in charge.
There is a difference between deliver to a circulation desk for use in the rooms of the library (presentation) and for loaning. Deliver to an office or at home is a different kind of service that implies loan. To distinguish deliver to circulation desk and self-pick up with open-access shelving we may need another method. -- JakobVoss 01:39, 23 October 2009 (PDT)
Hmm. I hear you. But we have some items for some patrons that can be checked out, but you've got to go get them from the stacks yourself. There are other items for certain patrons that can be checked out, and you can click a button and have them waiting at the circ desk. There are other items that can be checked out, and you can have them delivered to your office. The end result of all of these things could be considered a 'loan' -- but it matters to the user which of these things are available, the difference in convenience may effect their decision of whether to access the item at this time or not. How should this be encoded in DAIA so it can be presented to the user? I'm trying to take a stab at it, I hear your critique, but I'm still not sure the better way to do it.

Excerpt

http://purl.org/NET/daia-ext/excerpt

Request library staff to make a photocopy or scan of a part (chapter or article) of a physical item, which will them be emailed or delivered to the user.

Copying/Scaning as service makes sense. Is the act of copying the relevant service or the fact that you get only a part of the item as copy? -- JakobVoss 02:12, 29 September 2009 (PDT)
In my library, the nature of the service is that you only get part of the item AND you get choose what part. The act of copying isn't the relevant service, although I'm not sure how a library would provide a user-choice part of the item without copying, but if there's a way, that's fine! User:jrochkind
An item may have the fragment attribute but that would mean the library does only have a specific excerpt. So Excert looks like a reasonable service type. -- JakobVoss 01:39, 23 October 2009 (PDT)

Reference Client

There are many ways to interpret and display a DAIA result (traffic light, icons, detailed description, summary of items etc.). Maybe we can collect some best practise? -- JakobVoss 01:39, 23 October 2009 (PDT)
