EXIF and other metadata and imagesnippets

Yes, we would love to... If any one knows of any specific services, we would
love to include them if feasible/practical. 

As I mentioned the other day in my reply to Daniel, the Details tab inside
the application shows the
data that we do import from the image header itself if it exists (Creator,
keywords, title, subject, creator e-mails, websites, IPTC Scene code, other
XMP data, etc), we do preserve it as linked data and if it does not already
exist in an image you can add it and we also re-save it in the image header
(if the image has been uploaded and not just linked by URL). We also re-save
the IS html file about the image itself in the website field in the header,
thereby giving even greater reference back to the linked data. 

We do not currently display the EXIF (camera) data in the GUI, but we do not
strip it from the image header either. There is so much data potentially
included in image headers that can be displayed, but for this initial
release, I wanted to keep the GUI less cluttered. I am not opposed to using
any of it depending on what a customer or users seem to request the most.
Daniel has given us one data point on this, but we welcome others. I know
some photographers who use tools specifically to remove the EXIF data as
they do not want to share their camera settings so it's possible of course
to have additional layers in the IS GUI that would allow a greater selection
of what metadata is displayed and what is re-saved back into the header. 

In ImageSnippets, the creator field also contains a look-up feature for
allowing users to locate the person in Dbpedia or Yago (our main sources for
public LD IRIs)... 
If a person does not exist in one of these public datasets, the user can
create an entity for that person in the ImageSnippets dataset. We encourage
people to create IRI's and (for now) are quite willing to act as a host for
these new creations. If you have a foaf profile, you can also add your URI
in this field instead. 

In this way, ImageSnippets can be useful in allowing the relatively simple
creation of linked data entities for people which can in turn can be used by
other image processing (face recognition) tools. Conversely, of course, a
great feature would be to include the people tags if they are applied in
other software first, allowing the user to then match the people tags to
IRI's.

We have been exploring the import of the Flickr data in an improved way
(including
the tag data) for Flickr users or some other solution to this for a while
now. Daniel provided a link to the Flickr wrapper which I had looked at some
time ago, but I am confused by this...the wrapper seems to be for retrieving
images from Flickr that have tags that match dbPedia entities - what we
would actually need to use is their commercial api package for allowing
flickr images to be imported with their tag data. Unless I am mistaken here
and someone can point me in a different direction? I'm open to adding this
feature at some point if it seems that more users request it. 

As is, an image can be linked into IS with the Flickr URI but without it's
tags of course since they do not store them in the header. It is a shame
that Flickr strips the headers and of course other valuable information is
lost here as well.

We have had in mind all along that the application has uses other than for
social media, for example groups who may have large curated image
collections who could use ImageSnippets to manage collections
collaboratively build their own datasets containing their own specialized
vocabularies, publish their data directly from the application themselves
and/or we can publish the data as well. 

This use case has influenced the design (perhaps more so than the social
aspect). Though, as a photograper/artist myself, I'm quite interested in
also using the application to build my own RDFa image galleries - and the
feature to have a 'one-click' web gallery builder is in development now.  

Kingsley, I really appreciate you taking the time to explore the 
application and your comments and feedback!
