- Policy Control
Network Architecture using Metadata
- Rei Atarashi,
Shigeru Miyake and Fred Baker
- Abstract: Quality
of service (QoS) technology has been implemented to be applied to
new applications on the next-generation Internet. However, as new
applications such as P2P and stream application have many kinds of
features and requirements, some additional features should be added
to current QoS control technology. For example, they require a definition
of a single policy to operate QoS control in the management domain
consistently and efficiently. Policy definition for transport layer
in a domain and among domains is being discussed at IETF to set a
standard process, however detailed policy corresponding to the application
or contents information according to the application semantics has
not been discussed. Therefore we developed QoS policy control mechanism
using metadata which is defined as a structured data according to
the application semantics. Though metadata and transport mechanism
can be located into quite different positions in the concept of network
layers, we made them successfully collaborated by defining meta policy.
In this presentation, we describe our system architecture to define
a meta policy based on the requirements and information contents from
the application as a high level layer concept to be able to classify
the network behavior. Our approach enables to multiple QoS control
and collaboration among domains.
- Using Dublin
Core for an Online Knowledge Gateway for Industrial Design Education and
Research Activities
- Mida Boghetich,
Paolo Ciuccarelli, Perla Innocenti and Federico Vidari
- Abstract: This
presentation presents the development of Design_net, a knowledge-based
project to the online digital display, retrieval and archiving of
rich media resources for industrial design education and research.
The project addresses the needs of end-users (teachers and students)
and content providers interacting with the School of Design of the
Politecnico di Milano, moving from the assumption that conventional
modalities of archiving and presentation currently adopted by the
Politecnico and other academic institutions are not coherent with
design teaching, because the typical outputs of industrial design
process are 3D models or 2D graphics, not just texts or simple images.
The challenges, philosophy and methodology in creating this evolving
Web-based, cataloguing, multimedia knowledge-base of VR design resources
are discussed, along with description of the related system and prototype.
- Metadata hiding
tightly binding information to content
- Roberto Caldelli,
Franco Bartolini and Vito Cappellini
- Abstract: The
huge development of telecommunications infrastructures will strongly
push forward the diffusion of multimedia communication services. Anyway
the real effective development of such services will strongly depend
on the availability of a reliable platform for managing all the issues
related to the exchange of multimedia items among users through heterogeneous
networks and systems. Such a need is also witnessed by the disparate
initiative whose goal is to achieve Digital Items Identification and
Description. Some calls have been already issued regarding the identification
and description schemes: although it seems that metadata (and XML)
will have an important role for addressing this issue, anyway it is
evident that much work has still to be done. In this presentation,
a practical application which utilises a digital watermarking technique
to embed in a digital content metadata related to Intellectual Property
Rights (IPR), will be presented.
- Learning how
to Learn: Using the Dublin Core Metadata Element Set to Support Teachers
as Researchers
- Dr. Patrick
Carmichael
- Abstract: 'Learning
how to Learn' is a four-year Economic and Social Research Council
project involving staff from four universities (Cambridge, King's
College London, Reading and the Open University) and over forty schools
in the UK. It aims to provide knowledge that will be useful to classroom
teachers, school managers and to policy-makers about 'what works'
in real primary and secondary classrooms and schools and in educational
networks. The specific aspect of educational practice addressed is
formative assessment or 'assessment for learning', Qualified Dublin
Core is used to describe educational resources - published and unpublished
research, policy documents, teaching materials, and evidence (text,
images, audio and video) collected in classrooms. Other metadata sets
are also used within an RDF structure, including a novel vocabulary
developed in order to describe classroom activities and their relationship
to broader educational strategies and vCalendar's recurrence rule
grammar, which is used to describe repeated learning activities. The
explicit expression of relationships between classroom activities,
underlying strategies and evidence from educational research will
allow teachers to locate their own classroom experience in a broader
theoretical framework and provide support for them as they undertake
research in their own classrooms.
- Educational Metadata:
A Government of Canada Approach
- Marie-Claude
Côté
- Abstract: This
presentation describes the Government of Canada's approach to educational
metadata. The E-learning Sub-group, an interdepartmental committee
composed of metadata and e-learning experts and practitioners, is
developing an e-learning metadata standard to be used across all federal
institutions. The standard developed is to be compliant with the Government
of Canada Metadata Framework, which adopts the Dublin Core. The standard
must also support the new policy on continuous learning for the Canadian
public service, as well as consider impacts on the e-learning community
within and outside the federal government. In order to choose a metadata
standard that will best meet the Government of Canada's needs, the
E-learning Sub-group is undertaking a study on the state of e-learning
metadata in Canada and some other countries. The major metadata standards
and specifications used nationally and internationally will then be
assessed against a list of pre-established criteria.
- The Need for
a Meta-Tag Standard for Audio and Visual Materials
- Diana Dale and
Ron Rog
- Abstract: In
Canada, as elsewhere around the world, government is trying to move
into the Internet Age, to communicate more and more interactively
with an ever-increasing portion of the electorate and to increase
the interoperability of digitized media. The Canadian Government Online
Initiative, of which we are a part, is an example of this trend. To
facilitate access to our materials, we need metatags, metatags that,
by and large were originally set up to deal with print media. Thus,
we have been struggling in recent years to apply metadata to a test
database of Canadian cultural audio and visual clips that we call
"Heritage Line." We have followed many avenues for making our data
searchable and accessible. We have used the Dublin Core schema, both
with the qualified set of elements as well as the unqualified set.
Our problems arose specifically with respect to the elements 'type'
and 'format.' Mpeg-7 currently appears to offer a solution to our
problem.
- Enhancing end
user searching of HealthInsite
- Prue Deacon
- Abstract: HealthInsite
is the Australian federal government's Internet gateway to quality
health information. The site was an early adopter of Dublin Core and
makes extensive use of metadata in its navigation structure. HealthInsite
has two search options utilising the Verity search engine: a simple
text search and a metadata search. A third search option is the thesaurus
search which is most likely to be used by information specialists.
Additional functionality is being considered to improve subject searching
for end users. This presentation defines the research needed as background
to developing the system specifications. The need to consider the
whole information retrieval process is emphasised, and a clear role
for metadata specialists identified.
- Abstraction versus
Implementation: Issues in Formalizing the NIEHS Application Profile
- Corey A. Harper,
Jane Greenberg, Davenport W. Robertson and Ellen Leadem
- Abstract: This
presentation reports on problems encountered and decisions made during
the initial stages of formalizing and documenting an application profile
for the National Institute of Environmental Health Sciences (NIEHS)
Metdata Project. In order to facilitate as much interoperability as
possible, the project selected the Dublin Core as the basis on which
to build an optimal element set for the NIEHS metadata project. This
presentation discusses implementation issues, giving specific attention
to: when to declare element usage in an application profile rather
than defining a new element in a namespace; whether an application
profile can apply qualifiers from one namespace to elements from another;
and which version of an element that is defined in a variety of different
contexts should be used. It is determined that many of these questions
remain unanswered, and the ultimate decisions will, in part, depend
on standards yet to be established concerning XML and/or RDF serialization
of application profiles. The resulting discussion provides suggestions
toward refining, elaborating on and standardizing the concept and
implementation of application profiles.
- Integrating Learning
Objects into Learning Contexts
- I. T. Hawryszkiewycz
- Abstract: This
presentation describes learning objects in the context of a learning
process. It examines options of integrating learning objects into
context and supporting the integration with learning activities. The
presentation then examines the technology needed to support the creation
and utilization of learning objects. It suggests customizable portals
as the solution. It then illustrates an application to teaching.
- Metadata associated
Network Services and Capabilities
- Masatoshi Kawarasaki
and Junichi Kishigami
- Abstract: This
presentation proposes integrated framework architecture of content
delivery based on metadata associated network services and capabilities.
The basic concept of this architecture is a policy based content delivery
control using content metadata and user metadata. By making a network
being aware about content as well as user's requirement, more user-oriented
content delivery service can be achieved. The proposed architecture
includes "Metadata driven QoS control" and "Metadata driven One Source
Multi-Use". The former relates to Quality of Service (QoS) in terms
of content delivery service achieved by metadata-driven network resource
control, and the latter relates to content adaptations to meet usage
environment and user preference across a wide range of networks and
devices. By using proposed framework architecture, content delivery
service providers can establish particular policies to harmonize various
requirements described by metadata.
- Visual Representation
and Contextualization of Search Results: List and Matrix Browser
- Christoph Kunz
and Veit Botsch
- Abstract: We
present a new approach for the representation of search results in
a graphical user interface that allows navigating and exploring these
results. An interactive matrix display is used for showing the hyperlinks
of a site search or other search queries in different hierarchical
category systems. The results of a site search are not only shown
as a list, but also classified in an ontology-based category system.
So the user has the possibility to explore and navigate within the
results of his query. The system offers a flexible way to refine the
query by drilling down in the hierarchical structured categories.
The user can explore the results in one category with the so called
List Browser or in two categories at the same time with the so called
Matrix Browser (Ziegler et al. 2002). A familiar and well known interactive
tree widget is used for the presentation of the categories and located
hyperlinks, so the handling of the system is very intuitive.
- Development and
Application of Dublin Core Metadata Standards in Marathi
- Shubhada Nagarkar
and Harsha Parekh
- Abstract: To
enable Dublin Core metadata to become a global standard for locating
information on the Web, it is essential that such metadata be provided
in different languages and in a variety of scripts. This would enable
search and retrieval of Web documents in all languages. The presentation
reports an attempt to translate Dublin Core metadata elements into
Marathi language (the local language of Maharashtra State in India),
render them in Devnagari script and apply them to a significant section
of Marathi literature - viz. the writings of one of the "saint-poets"
of the Middle Ages. A group of "saint-poets" in Maharashtra from the
13th century (e.g. Jnandev 1275-96) to the 17th century (e.g. Tukaram
1608-90) helped establish the 'Bhakti' (devotional) school of Hinduism
in Western India and assisted in its spread from southern to northern
India. Even today, the lives of the saint-poets and their literature
continue to inspire a large section of the Marathi speaking population
and provide them with emotional solace. As such, their writings constitute
an important segment of Marathi literature and researchers from all
over the world are engaged in studying it. The original writings (including
the early handwritten manuscripts) and commentaries on them are scattered
at different places in India and are now beginning to make an appearance
on the Web. Our efforts are to create a web based database and to
assign Dublin Core international metadata standards rendered in Marathi
for cataloguing the literature of one of the prominent "saint-poets"
- Chokha Mela - available in print and electronic format as well as
on Internet. This is conceived as part of a larger project of organizing
all the literature of the "saint-poets". The Marathi metadata elements
will enable search and retrieval in the original language and script.
Readers can download online full text documents if available. The
database will be available online via PuneNet at http://punenet.ernet.in
in the near future. It is also envisaged that the database will develop
cooperatively and online data entry and data correction facility will
be provided if necessary.
- Why is Accessibility
Metadata Proving Difficult?
- Liddy Nevile
- Abstract: Accessibility
metadata is simply metadata that describes the accessibility of resources
and services, usually those on, or available through, the web. Awareness
of widespread web content inaccessibility led to work being done to
develop guidelines for authors and others to make sure that content
would be more accessible to those with special access needs, especially
those with disabilities who were being disenfranchised by their lack
of access to the web. Currently, work is being done to find ways of
signalling the degree of accessibility of resources, and ways of matching
resources to searches and people. In addition, accessibility metadata
could be used to repair some inaccessibility problems on the fly.
This presentation describes some of the work being done and the problems
that have contributed to make the progress comparatively slow.
- Subject Access
Metadata on the French Web: Trends
- Ewa Nieszkowska
- Abstract: The
article presents the general situation of metadata in France and the
projects (in progress or realised) of the use of documentary languages
as subject metadata. The article gives the reasons for the choice
of human indexing instead of search engines and also describes one
example of indexing language enhancement in order to make it more
user friendly. The presentation focuses on a possible interaction
between the use of indexing languages as subject metadata and the
semi-automatic maintenance of indexing languages themselves. This
approach is not really wide-spread yet. The fact is, however, that
the manual maintenance is costly in terms of human resources. It could
be considerably simplified thanks to corpuses of documents indexed
with subject metadata.
- A Proposal for
a Flexible Validation Method for Exchange of Metadata between Heterogeneous
Systems by Using the Concept of MicroSchema
- Erlend Øverby
and Jens Vindvad
- Abstract: In
this presentation, a new method to solve the validation problem that
arises when exchanging information between heterogeneous systems with
different vocabularies is proposed. The problem of validation is addressed
by introducing the concepts of MicroSchema, used in a namespace environment.
To demonstrate and test the concept a new flexible XML-model for exchange
of research documentation in Current Research Information Systems
(CRIS) has been developed and proposed. A working XML-exchange model
for metadata exchange between different CRIS and between with library
systems and CRIS are described. The working model is limited to documentation
produced by the researchers. The ideas, XML-model and construction
proposed and used in the working model are extensible, and can be
expanded to the whole field of research documentation in addition
to other fields.
- What's the Use
of DC.Type?
- Simon Pockley
- Abstract: Type
has come to the fore as one of the primary organizing elements in
the design of input forms suitable for the generation of high quality
moving image metadata. A lack of semantic precision in both the definition
and in the conceptual complexity of DC.Type's encoding scheme has
prompted a re-evaluation of its usefulness as an element to be populated
for interchange and discovery. In order to introduce precision to
this element, a distinction is made between subject-based descriptors
(genres), object based descriptors (forms), and manifestations or
format-based descriptors (formats). A DCT2 vocabulary is proposed
for DC.Type as a point of discussion for facilitating the deployment
of domain specific encoding schemes and for filling gaps in the current
list of terms.
- Using Dublin
Core for DISCOVER: a New Zealand visual art and music resource for schools
- Karen Rollitt,
Adrienne Kebbell and Douglas Campbell
- Abstract: DISCOVER
is a web resource supporting the visual arts and music curriculum
in New Zealand schools. It contains 2500 multimedia items from the
collections of the Alexander Turnbull Library, which holds the national
cultural heritage collections, and 300 resources from other sources.
The product uses a metadata scheme that combines simple (unqualified)
DC and qualified DC, EAD and local extensions expressed in XML and
uses the RDF framework proposed by DCMI for expressing qualified DC
in RDF/XML. This metadata schema will continue to evolve to support
interchange of the NLNZ's digital resources within the library, archival
and education communities.
