Right? OK, so.
It keeps on jumping that to the next slide.
OK, so within my sort of small section here,
I'm going to talk about some of
the smaller demonstrators or
experiments that were developed,
one of which on the back of Simplesite
and one of which has become after that,
to answer two of the questions that were
raised at the start of the project. So.
Basically discovering IIIF content.
I mean IIIF as most of you will
probably know the the international
Image interoperability framework
can help provide Open Access to a
wealth of images from institutions
across the world all using the same
free shared tools and services.
The IIIF Consortium itself
provides very nice guide which brings
together a great list of these
institutions and showing how you
can find published live resources.
Many of these institutions actually
provide well documented APIs to
allow more complex searching.
To find the paintings or images
or objects in the collection that
you're actually required for your
research or your activity.
Now,
the thing about making use of these
open APIs is they're great.
There's lots of information in there,
but they can be quite complex,
so this is just a quick snapshot
of the results from the National
Gallery Washington API,
which I've used quite a lot,
which is really good,
but it does take a little while to
learn the documentation because it
is just quite a complex system, so.
The question was,
is using the current data that's
being provided by the National
Gallery Washington or the other
in other institutions?
Can it be made easier just to get a
preview of the trip if contents in there?
So here you actually need a long URL.
There is a web page to do this as well,
but if you're wanting to pull the data
directly to make use of and to do work with,
you need to construct this big URL and
then you actually get all of this data back.
You need to go through it to find the
IIIF stuff which is actually named.
There.
You got IIIF manifest URL.
And the canvas ideas.
You've got some IIIF information
in there and to get them out
to do something with it.
So the idea was to develop a simple
if discovery system and it was carried
out to demonstrate what could be done.
So for individual institutions or across
multiple collections at the same time.
This work was supported by
three collaborations between
three different projects.
The practical IIIF project,
the EU Horizon 2020 Shock project and the
EU horizon 2020 I period HS project now.
That is the link to the live site.
It does work,
it's up and running and you can explore
that in your own time afterwards.
Now this is how it basically works,
so you have a website where a user
can have a keyword search and this
goes to a simple discovery endpoint.
Now that endpoint then reformats
that query into the complex
query required for a given institutional API.
You get the results.
These custom results come back to the
end point, which then reformats them
into a simple list of resources and
pushes them back to a standard viewer.
So what the user sees is a keyword
search and the IIIF results.
Even though you're making use of
all of the powerful API options
from the different institutions,
so this is the current website I'm
not going to the lot of into the
technical details of how it works.
There is a lot of documentation
on the web page explaining that.
And we just want to sort of
show how it works today,
but the user interface is a simple
search box with a limit and page
number option and the viewer default
option either Openc Dragon or Mirador,
and in this case you can search
across seven different collections.
At the moment the Art Institute
of Chicago National Gallery,
National Gallery of Art, Washington.
The Smithsonian Stats Museum
for Kunst in Denmark,
the Vienna and the welcome trust.
And if you do a search for C,
it returns you
187,554 objects.
A lot of these are coming from the
Smithsonian and you can explore.
I mean, it's just open C dragon.
You can zoom in and zoom out and
explore the images as you require,
but openc regard on its own doesn't
tend to give you any context of what
the images are and where they're from.
So by clicking on the last
icon on the top right,
you can actually then Scroll down the
list and get direct connections to
the individual images as required.
Now Openc Dragon, as I said,
provides great for exploring
large sets of zooming images,
but it's not so good for metadata
and context now, Mirador.
Another IIIF compliant viewer
provides a lot of options for
metadata and context for the images,
so depending on the needs of a user,
the simple discovery system
allows you to toggle back and
forward between the two options,
so you can just push on the mirror door
button and you'll get the mirror viewer
or push back to get the open sea dragon,
you can jump back and forth between the two,
and mirrored are obviously gives the
option to see all of the information
about the individual objects and
the images that are inside the.
Search result now the simple IIIF
discovery system with a little while
ago it was created on the back of the
simple site system and mentioned all
of the code is up on GitHub and there
is an archive on zenodo for people to use.
And all of these links will be available
in the material we upload and save on the
public website at the end of the webinar.
Now the next thing I was wanting
to talk about was one of the issues
within the National Gallery,
which is where I work is.
We look to try and support exhibitions
and publications with high resolution
images and provide more content
for guest visitors and users.
So over the last ten years or so,
the National Gallery has been publicly
presenting high resolution images
to support some of these activities.
These sets of images have been
put together to provide additional
content for exhibitions, publications,
and research projects.
Now this current or old.
System was based on the spoke IIP
Image Viewer which I built a number
of years ago now and as part of the
practical IIIF project we wanted
to upgrade that to a new system that
made use of the layer presentation
version three API and the new specifications.
So this is the new system.
This is how it looks.
It's styled a lot of based on Bootstrap,
which is a JavaScript library CSS.
Now the structure of the old system
was based on a hierarchical.
Group of images and type titles
and descriptions of those images,
and these are all stored in a MySQL database.
Now this was easily replicated
using groups of Traer manifests,
which is a group of images with
a title and
a description and supporting metadata.
These groups of manifests can then be
packaged together into leaf collections,
so a IIIF collection is a selection
of subcollections or sub manifests.
So the simple system was created
through our users to explore a
complex of collection and then
display the the results in Mirador.
So that's the link to the live site.
I'll leave it as a title in the
next few slides so people can
have a look if you'd like,
but effectively what it does is it's one
page of PHP that looks at the current
time players collection or manifest,
pulls out the details of titles
and any metadata that's in there
and displays them in a nice,
user-friendly, simple screen.
On any child resources,
be they collections or
manifests are listed below.
Quite similar to some of the functionality
that's available in Mirador,
but in this case,
each of the steps have their
own distinct URL,
so you can reference or stop or
start at any particular point in
a complex IIIF collection.
And you can look at them either
as an interactive list shown here
and that happens when there's at
least one collection in there.
You get an interactive list or.
My list of manifests can be
dropped straight into mirrored or
as you can see here,
so you can then explore the images
as required and as you want to and
explore them so this particular set of
images was put together in relation to
exhibition on brochu's lesson in drawing.
So there's quite a lot of different
drawings in there in relation
to one particular painting.
Now the addition is.
This is one of the things we've been
doing is supporting the publications,
so the National Gallery Technical
is one of the publications we
produced every year looking at the
technical examination of paintings
and a number of the research that
comes out of the National Gallery.
So the old system provided you a link to
where you could find a PDF of the article.
So this new system actually puts it in line.
So if additional metadata is
added to the IIIF manifest
to indicate a linked PDF.
System can then spot that and will pull
in and load in the PDF directly and
present it just next to the images.
So in this case you can zoom in to
this thumbnail as you were reading
the particular article there on
Reynolds painting technique,
and that's worked really smoothly now.
The system is currently optimized
to exploit additional where the
data in the IIIF document to
define the bread crumbs so you can
see at the top there's a breadcrumb
trail taking you from the home page,
right the way down to the given
manner set of manifests you're in,
and all of the collections nested
collections back up to the top,
and this comes from the metadata
that's stored in the system.
You can make the system work from
any IIIF collection.
It doesn't work at the moment because
the development work I was doing,
but some additional work is going to be
required to make that a bit more robust to
allow you to just drop any collection in
there and explore it as you as you want.
Now the last thing I wanted to say before
I hand on is as part of this work and the
result of an interesting discussion on Slack.
So I put the question is if one has a
big complex IIIF collection.
Is there a way to quickly
preview all of the images?
It without needing to go up and down all
those nested collections of manifests,
so the actual screen shot on the front page
is from an example of how you can do that.
So we built a small collection previewer.
So yes, so this is the link of the previewer,
and this does work with.
We've tested it with a number of IIIF
collections in version two and three,
and the ones I've used work so far,
it seems pretty good,
and what it does is it will load you all of
the images referenced in that collection.
Or in those manifests into open sea Dragon.
So here you can see an example.
All of the images that are
actually referenced in the.
The IIIF collection Explorer
that I've just presented there.
It's about just shy of 1500 now.
This does work quite well.
It can take a little while for
them to load in.
If you're loading in that
sort of number of images.
It can be a little slow.
It's currently hard,
limited to 2000 because things started to
get a little problematic at that point,
but it is possible to put larger
ones in there,
so future work was going to look
at potentially combining this with
the two player discovery that I
mentioned at the start the GUI so
that people might be able to have
limits and pages and offsets so
that you can actually work your way
through larger collections of images.
And I will stop there.
So that's the IIIF collection
preview IIIF Collection Explorer
and simple IIIF discovery.
Thank you.
