WG 2 Workshop on
New Metadata
Standards
May 23, 2008
Sydney Australia
Leader: Denise Warzel
Many organizations have recognized the need to develop and share programmatically
accessible terminologies, services and data collection forms. This workshop will focus on
building a consensus and plan for advancing the development of new metadata registry
standards for these types of objects: Services, Terminologies and Forms.
To enable data processing systems to be written to discover and use these types of
resources accurate, unambiguous and verifiable metadata is a prerequisite. With
appropriate metadata standards for these types of objects, systems could be designed to
allow owners to register and share electronically the essential characteristics necessary for
common understanding of what and how these resources are intended for use. While the
ISO/IEC 11179 addresses unambiguous representation and registration of data elements,
no such standard exists for these important objects that are essential for developing
interoperable information systems. A standard metadata framework to describe the
essentialcharacteristics of these types of objects in ways that can be compared and
interpreted is needed.
The envisioned metadata standards would be similar to the ISO/IEC 11179 Metadata
Registries standard Part 3 in which the registry and basic attributes of each type of object
are defined and can be specified and registered in a metadata registry.
This session will facilitate developing a common understanding of some of these
characteristics for each type of object. Participants will share existing metamodels and
emerging specifications, discuss common needs, approaches and priorities and possible
next steps that could lead to the development of new ISO standards in these areas.
This session would be of interest to information developers, information managers, data
administrators, standards developers and others who are responsible for designing
systems in which these types of metadata objects are understandable and shareable.
Many organizations have recognized the need to develop and share programmatically accessible terminologies,
services and data collection forms. This workshop will focus on building a consensus and plan for advancing the development of new
metadata registry standards for these types of objects: Services, Terminologies and Forms.
Type of Metadata Standard: (Service, Terminology, Form or Other):
Existing/Recommended metamodel:
Benefits:
Use Cases/Justification if this standard existed:
Known initiatives/individuals that could be pooled to create a Functional Specification:
Plans for Implementation:
Suggested next steps if known:
Goals for Today
• Discuss new areas for development of metadata
standards
• Specifically: Terminology, Forms, Services
• Reach common understanding about what each of these
metamodels would describe (agree what we mean by
“Terminology”, “Forms”, “Services”)
• Reach consensus on priorities/areas of common
interests
• Learn how to progress something into a new standard
• Form a Strategy for progressing these new standads

Areas of Interest
• Registry Metamodel
– Profiles that would allow registry operators to ‘declare’
themselves, provide attributes that would enable others to
understand certain characteristics about the registry, such as
business rules, naming conventions, contact information etc.
– Issue 127: 2005 Global Attributes for a Registry to be used with
an ROR
– (ISO 29002)
– What is contained in the Registry (e.g. What type of registry is it?
Image Registry, Service Registry, 11179 Metadata Registry, etc)
– Establish “Trust”
• Interest is registry for CWM mappings (Baba)
‘Terminology’
• There are different types of terminologies
• This would cover all types of
terminologies:
• Taxonomies, Formal Ontologies,
Standardized list of terms, Vocabularies,
Dictionaries, etc.
• The metadata would describe the
Terminology as a WHOLE – (NOT the
model for the terms in the terminology)
Terminology Issues
• Agree on a common definition of ‘Terminology’
– Look at TC 37 work (Sue Ellen Wright)
• Add proper Provenance class
• Related Work:
– Registry for Knowledge Organization Systems (NKOS) – Gail
Hodge
– ‘Rights’ – UMLS has both public and restricted content
– UK Joint Information Systems committee (JISC) – Dennis
Nicolson(?), Doug Tudhope
– NCBO – BioPortal – resource quality, attributes
– Government Terminology Services – each country has some
terminologies they are serving and have an implicit metamodel
that could be harmonized

Areas of Interest
• Services Metamodel
– Profiles that would allow a Service Registry
operators to ‘declare’ themselves, provide
attributes that would enable others to
understand certain characteristics about the
registry, such as business rules, naming
conventions, contact information etc
– Establish “Trust”
‘Service’ definition
• OASIS (organization) defines service as "a
mechanism to enable access to one or
more capabilities, where the access is
provided using a prescribed interface and
is exercised consistent with constraints
and policies as specified by the service
description."
Service Metadata Issues
• myGrid Service Model
• caGrid Service Metamodel
• Need a way to describe a “Registry
Service”?? Should use WSDL – service
metadata would provide a way to
standardize a description of the described
in a WSDL
• IBM has introduced Service Science as a
new curriculum – may have some
information that would be compatible

Service Types
• Domain: Performs scientific function
• Shim: Does not perform scientific function,
but is needed to make one service work
with another
– E.g.

Bioinformatics Research and Applications, Vol. x, No. x, 200x
myGRID Service Operation:
•Operation.resource
•Operation.method (algorithm)
•Operation.task
These concepts could come from
myGrid ontology
The concepts for each “Input” could come from
the semantics registered for the UML class

Comparison of myGrid semantics and caGrid Semantics
myGRID semantic categories
•Informatics. captures the key concepts of data, data
structures, databases and metadata. The data and metadata
hierarchies in the ontology contain this information.
• Bioinformatics. This builds on informatics as well as data
and metadata, there are domain-specific data sources
(e.g., the model organism sequencing databases), and
domain-specific algorithms for searching and analysing
data (e.g., the sequence alignment algorithm, clustalw). The
algorithm and data_resource hierarchies contain this
information.
• Molecular biology. This includes the higher level concepts
used to describe the bioinformatics data types used as
inputs and outputs in services. These concepts include
examples such as, protein sequence, and nucleic acid
sequence.
• Tasks. A hierarchy describing the generic tasks a service
operation can perform. Examples include retrieving,
displaying and aligning.
• Formats. A hierarchy describing bioinformatics file formats.
For example, fasta format for sequence data, or phylip
format for phylogenetic data.
•Informatics. Not sure if we have a corollary or need this.
• Bioinformatics. We could probably use theirs for attaching a
concept to Operation algorithm
• Molecular biology. We have this already, its the concepts
associated with the UML Class level
• Tasks. We could probably use theirs for Operation task.
• Formats. Probably useful, this is at the Service level – not
sure if this is similar to the ‘dimensionality’ attribute we have at
the input/output level?

“Forms” Description
• A structured set of metadata for the collection of information and for
the ‘form’ itself
• There are various types of forms
– Statistical forms
– Surveys, Questionnaires
– Population Science Measures
• Eg quality of life
• Link to Rules for Form Completion
• Rights – can the form be reused? By whom? What is the process for
authorization, etc.
• Includes Standard way to describe minimal Rendering information
• To describes how the form looks
• ‘Behavior’ – skip pattern
– Form Structure
• Standard way to associate the semantics of the Question and
Answer Set (e.g. to associate an item on the form with a 11179 Data
Element, DEC or Value Domain
Forms MetaModel
Related Projects
• OASIS
• UN/CEFACT – Forms Metamodel
– UN eDocs – Cross Border Trade ‘form templates’ –
may have an implicit form metamodel
– ISO 15000-5 ebXML
– ISO 7372
– Adobe pdf form metamodel
– MS InfoPath – has a metamodel for their forms
– XForms - language for representing forms

Metadata Standards Development
• SC 32 and WG 2 Options for progressing these
– ServiceMetadata, Forms Metadata, Terminology Metadata and Global Registry
Metadata (RoR - Issue 127)
– Also need a Service Specification for Registries
– Work with Issue 127, or create another issue to put into 11179
– WG 2 ‘Study Period’
• Look at this and decide what approach we should take
• New part of 11179? New Standard?
• ‘Study Period’ involves more open participation, not as formal as a WG 2
meeting
• Could be proposed as a new Study Period next week as a ‘Resolution’
– Needs a Leader, provides an opportunity to circulate something for people to
“sign-up” - Could Report back at the next WG 2 meeting in the Winter 2008 (5-8
months)
