Expose services of the IIIF API in version 3.0

CSIPiemonte

Hi, we need to expose some services of the IIIF API in version 3.0 to an external system.
Will this version be supported in CA 2.0?

seth

Yes

Hi @seth could you point us in the right direction on how to access IIIF manifests? Exposing a IIIF collection would be great as well! Thanks =)

kbecker

FWIW for us it would be enough to initially export a IIIF collection once.

seth

What would you consider a "IIIF collection" to be in the context of a CollectiveAccess-based catalogue? Is it composed of the items (objects) related to a collection-level record? Or objects in a hierarchy? Multiple object representations attached to a single object record? Or something else?

I think for starters it would be nice to output a IIIF-collection of all objects of a specific type for example. It could be configurable and be accessible with a URL like for example the bavarian state library in germany does: https://api.digitale-sammlungen.de/iiif/presentation/v2/collection/top

it could be https://www.your-collectiveaccess-instance.com/service.php/IIIF/presentation/v2/yourcollectionname/top

kbecker

Hi @seth , it would be even be sufficient for me if there was a way to get IIIF Manifests for objects or some information on how you plan to endorse IIIF in the furture (it's used for Mirador in CA for example, why don't make it a first class citizen?)

Thanks, Karl

Access IIIF Presentation API manifests:

https://<pawtucket_url>/service.php/IIIF/manifest/ca_objects:<object_id>

Hi, we're working on latest release of Providence (2.0.3).

we tried to obtain object resource IIIF manifest file via this URL:

<protocol>://<hostname>/<context>/service.php/IIIF/manifest/<id>

the result was:

Fatal error: Uncaught TypeError: IIIFService::manifest(): Argument #2 ($options) must be of type ?array, RequestHTTP given, called in <local_path>/app/service/controllers/IIIFController.php on line 59 and defined in <local_path>/app/lib/Service/IIIFService.php:620 Stack trace: #0 <local_path>/app/service/controllers/IIIFController.php(59): IIIFService::manifest() #1 <local_path>/app/lib/Controller/RequestDispatcher.php(289): IIIFController->manifest() #2 <local_path>/app/lib/Controller/AppController.php(108): RequestDispatcher->dispatch() #3 <local_path>/service.php(55): AppController->dispatch() #4 {main} thrown in <local_path>/app/lib/Service/IIIFService.php on line 620

Is the url I tried wrong? Or something wrong in the implementation?
any suggestions please?

thank you very much

kbecker

Can you give an example? for us it's important to add ca_objects: before the <object_id>, like: https://db.games-archive.org/service.php/IIIF/manifest/ca_objects:1101 Also do you have a IIIF.conf? See https://github.com/collectiveaccess/pawtucket2/blob/af8f2a53e358a809f74f4d2d9b19519f6b7c10c2/themes/default/conf/iiif.conf

kbecker

thanks @kbecker for the suggestions, but:

1) used ca_object: in url, before the <object_id>:

https://<providence_url>/service.php/IIIF/manifest/ca_objects:<object_id>

but still doesn't work

2) regarding the iiif.conf file, it is not present in the 2.0.3 distribution of providence => we tried to copy it under the app/conf folder of the installation on our server, but the result does not change

kbecker

CSIPiemonte This might only work with Pawtucket2 @seth ?

CSIPiemonte

Hi,
on 1.7.16 the service call worked on providence without being forced to install Pawtucket2.
I would expect it to work on 2 as well...

kbecker

IIIF Service was not present in 1.7.6: https://github.com/collectiveaccess/providence/blob/1.7.6/app/lib/Service/IIIFService.php

CSIPiemonte

our prod installation is 1.7.16, we are working to migrate to 2.0.3 in prod and we need to use IIIF services to interface with external application to which we need to give media through IIIF service

https://github.com/collectiveaccess/providence/blob/1.7.16/app/lib/Service/IIIFService.php

CSIPiemonte

Hi,
we managed to get the media with IIIF services on our dev environment 2.0.4 providence.
There is an authentication procedure to get the token described in:
https://manual.collectiveaccess.org/providence/developer/web_service_api.html

The correct url is for example when we get the representation media:
/service.php/IIIF/representation:226145/full/full/0/default.jpg?authToken={token}

We reported an issue with the mimtype that the method
$response->setContentType($vs_mimetype); seems not to work
in the dispatch function

#1708

Thanks to all
