Why embed data in images?
This is what we hear…
•There are too many standards
•There are too many fields
•It’s too much work to add all that data
•The labels change depending on the software
•We do things our own way
•There’s no budget for improving our data
•Photographers do pictures not data

Beyond DAM, beyond web …
•Photographers can take control of data for
their images
•Workflow can be made easier
•Embedded data can be used in practical ways
by the public

Photographers
•You have the object or artwork
•You can add data at source
•Photographers need not be locked out of data
workflow (even if they don’t have DAM)

SCREM PROJECT aims
•Make data entry easier at all points in the
workflow
•Extend IPTC fields for heritage metadata
•Encourage people to use the fields available
•Use existing standards to create a practical
schema (SCREM) for embedding and reading
heritage data in images
Data schemas
COLLECTIONS
MANAGEMENT
SCREM XMP panel IPTC
Starts with object
description
Treats object and image
separately and relates to
image workflow
Starts with image
description
Detailed description of
object and its
administration including
movements, exhibition
condition and provenance
More granular data for
object than IPTC, but not
so detailed as
COLLECTIONS
MANAGEMENT.
Granular data about image
and its administration, and
includes key details of
artworks and object
depicted
Used by institutions Can be used by institutions
to exchange granular data
about image and work
Used in image workflow
and publishing/viewing
environment

Granularity principle
How do you want it?
•Granular means you can have your
data how you want it (lumps or
granules)
•Solid lumps can’t be split
Criteria for IPTC candidates
YES if
•about the digital image
•needed to identify source, creator and
copyright of artwork
•links to more granular data on the web
•descriptive data useful for end user
•useful for image retrieval
•can be mapped from other schemas
Criteria for IPTC candidates
NO if
•about movement, condition, exhibition of
work, except where needed for accreditation
•specific to institution holding the work and
not needed by outside users
•detailed provenance (former owners etc)
•about monetary value or insurance of work
Consultation –with interest group
Image libraries, collections management cataloguers, software
providers
Consultation
•We consulted on the scope of the project ,
and the fields needed
•There were 3 iterations, and some areas
where fields were concatenated
Issues
•We could not add unlimited number of fields
•Recognition that authoritative data is held in
collections management system
•Persistence of data -snapshot or link?
•Human or machine readable?
•Technical XMP issues
Principles
•Support registry entries and machine readable data
•Display human readable data
•Link to authoritative sources where possible
•Cater for non-art objects and the way they are
sourced
•Include ‘display’ and ‘search’ metadata

Once we have the data fields, what
then?
•Let people know they exist
•Encourage software adoption
•Get people using them
The usual comment
Speed things up…. create a panel !
•Create a panel!

The compatibility question
•Infinite multiple values don’t
work with spreadsheet data
exchange
•Compatibility mode has
limited number of values (eg
up to 3 Creators)
•Note that you can hide fields
you don’t want to see!
SCREM panel
•More data fields than IPTC
•Uses IPTC AO fields
•LIDO style event based
schema
•Has fields useful to
photographers eg
inscription
•Aims to be user friendly

SCREM panel –event based
Free or commercial….
•Identification is important
•Rights are important
•Descriptive information can be used
•Attribution is about public access to
information
When to embed
WHEN IT AIDS THE WORKFLOW
•Transfering data to the database environment
•Data transfer between departments or
institutions (sometimes)
•Data transfer between image libraries for
commercial sales
When to embed
ALWAYS
•When the image ‘escapes’ from the database
•Any image that can be control-click
downloaded from the web
SCREM
•Uses fields from existing schemas
•Uses some IPTC fields
•Enables exchange of richer data
Labels and standards
•There are too many standards
Use existing standards
•It’s too much work to add all that data
Use automation, hide what you don’t need
•The labels change depending on the software
Make demands on software companies -get used to mapping
•We do things our own way
Fine, but can you share your data?
•There’s no budget for improving our data
You can get it right from now on for very little cost
•Photographers do pictures not data
Not true!
What have we learned about creating
and using standards ?
•Create a small group for the project
•Consult with practitioners
•Provide practical tools for use
•Use open linked data
•Hold tight to the vision –this is a long game
Start Now!
