What we do
• dance• theatre• music• film• broadcast arts
The PADS works with performance practitioners, archives, academics, and the performance industries and their representatives… the PADS collects, documents, preserves and promotes the use of digital resources in teaching, learning and research.

Some key questions
• What am I describing?
• How does cataloguing change when I’m describing digital objects?
• What concepts do I need to pin down?
• How will users access my resources?
• How will my resources interoperate with others?
Performing Arts Data Service
How does cataloguing change when I’m describing digital objects?
Content? Type? Format? Location? Access?

This simple model seems to work well for discovery of simple digital objects, but…
Performing Arts Data Service
What are we actually cataloguing?
Cataloguing a ‘simple’ data resource...
1. A discrete digital object
2. A discrete digital object which acts as a surrogate for a physical object
3. A discrete digital object which acts as a surrogate for a physical object and which is one amongst a number of closely-related objects
4. A discrete digital object which acts as a exemplar for a collection of physical objects and which is embedded in a bibliographic data resource
Decisions about cataloguing are almost always locally-driven, must respond to the needs of a perceived user group or groups and must reflect the resources available… these resources may include personal skills, information sources, available technology and time.
Performing Arts Data Service
Standards
These activities should be defined by standards:
Structuring the data:
Field names
Field types
Relationships
Describing the resource:
For resource discovery
For resource management
For preservation
Each record should be a conflation of different standards and working practices…
Performing Arts Data Service
Which standards?
Problems with standards:
There are too many competing standards
Standards do different jobs for different user communities and different data types
A successful data resource must make use of a variety of different standards for both structuring the data and describing the resource
Creators are often tempted to use standards in an inappropriate way for ease
A successful data resource may:
Include field types from a variety of standards (e.g. Dublin Core, ISAD) as well as local fields
Populate the fields using AACR2
ISO etc. as well as specialised cataloguing practice for e.g. music
Use standard terminology, controlled vocabularies, name thesauri, classification schemes
Performing Arts Data Service
The Dublin Core
• Most creators of electronic resources are now encouraged to use the Dublin Core set of fields to describe their resources
• The Dublin Core should be used to facilitate:• Resource discovery• High-level interoperability
• It is not intended to:• Contain information specifically for management or preservation of the
resource• Replace accepted cataloguing practice• Support granular, sophisticated interoperability between disparate
resources

Some key problems
‘Format’
Non-standard media (e.g. video, audio, music score, play script, choreographic notation etc.)
Complicated or ill-defined rules for cataloguing media types
Lack of guidelines for dealing with multiple parts, excerpts etc.
Multiplicity of local solutions
‘Subject’Lack of cohesive community identity
Complicated or ill-defined rules for describing subjects, events and concepts
Poor or ill-defined classification schemes, controlled vocabularies and thesauri
Multiplicity of local solutions
And... Tendency to confuse or conflate ‘format’ with ‘subject’
Tendency to conflate multiple instances of the object
Performing Arts Data Service
Performing arts documentation
Always the same old problems…
Who? Lack of standard names, international names...
Chaykovsky or Tchaikovsky
Bernard Shaw or George Bernard Shaw or Shaw, G.B.
Where? Same place, different name...
Theatre Royal Bristol or Bristol Old Vic or Bristol New Vic...
What? Same work, many identites...
Eroica or Symphony no.3 Eb op.55
Performing Arts Data Service
What do users want?
An academic may seek...Russian chamber music of the early 19th century
A performer may want...Music for violin, cello, bassoon, horn and harp
A teacher may want...Advanced grade pieces between 1750 and 1900
A producer may be looking for...19th century salon music
They will all be happy with… Glinka’s Serenade on themes from Donizetti’s ‘Anna Bolena’ - but how can we make sure that they find it?
Performing Arts Data Service
What information?
Which classification scheme?
Dewey (including Reeves/McColvin revised Dewey)?
UDC?
LC?
Specialist subject-specific identifiers?
(opus numbers, scholarly works, in-house schema)
Which name authority list?
New Grove Dictionaries, AllMedia Guides, IMDB
Which naming convention?
AACR2?
Performing Arts Data Service
Performing arts classification
Classification schemes are not enough…
Are we describing the ‘medium’ or the ‘intellectual content’?
What is the ‘subject’ of this work?
What do users need to find?
Score or sound recording or music literature?

What is a collection?
• A database? A selection of images? A digital text?
• Is ‘the collection’ a static or dynamic concept? Who defines what fits together?
• Does ‘collection’ mean physical location? Is this meaningful when your archive is virtual?
• How should we control the levels at which documentation is applied?

Describing the performance
Is ‘the performance’ the obvious ‘collection-level’?
- performing arts essentially people, activity and event-related
- many collections are of performance-related ephemera
- can offer useful parallels for other subject areas e.g. archaeology
What are the drawbacks?
- not all performance data is specifically event-related
- existing standards not designed to describe temporal concepts
- multiple creators, dates, publishers
- defining location complex
