Prehistory - The Semantic Grid Report 2001

• At this time, there are a number of grid
  applications being developed and there is a whole
  raft of computer technologies that provide
  fragments of the necessary functionality.
• However there is currently a major gap between
  these endeavours and the vision of e-Science in
  which there is a high degree of easy-to-use and
  seamless automation and in which there are
  flexible collaborations and computations on a
  global scale.

From e-Science to e-Research

• Not just new Science
• e-Social Science
• e-Humanities
• e-Arts
• e-Research
• e-Business
• e-Anything
• And new disciplines!

• Researchers working in all disciplines are faced
  daily with a wide variety of tasks necessary to
  sustain and progress their research activity
• These involve the analytical aspects of their
  work, access to resources, collaboration with
  fellow researchers, and project management and
  admin
• These tasks rapidly increase in scale and
  complexity as collaborations grow larger, become
  more geographically distributed and involve a
  wider range of disciplines

HASTAC
Humanities, Arts, Science and Technology
Advanced Collaboratory

• HASTAC is an international, interdisciplinary
  consortium which seeks to create, develop,
  advance and utilize a broad range of leading
  computing and information systems while
  contributing to an understanding of the
  interconnections between the human sciences,
  natural sciences, arts, and technology in a
  complex global society

NGG Report European Grid Research 2005-10

• The expert group convened in two meetings at
  Brussels to provide an expert's view on the 5 to
  7 year research priorities for the European
  context. This group's opinion was that current
  Grid implementations lack many essential
  capabilities, which would enable the vision of
  complete resource virtualization.
• Three perspectives are defined to envision Next
  Generation Grid(s) (NGG) the end-user vision in
  which the simplicity of the Grid is exemplified
  the architectural vision of a large-scale,
  self-organizing network and the software vision
  of a programmable system.
• Each of these visions is described in detail to
  support the assignment of priorities to the
  research agenda. In order to realize those
  visions, a number of research priorities have
  been identified. They fall into three categories,
  the first one considering the properties of a
  Next Generation Grid, the second one specifying
  the facilities provided by an NGG, and the third
  one comprising the models that are needed for
  orchestrating Grid services.

Charter Goals

• The goal of this RG is to realise the added value
  of Semantic Web technologies for Grid users and
  developers. When the scientist seeks answers to
  problems such as those below, we wish to have the
  answer obtained by automatic linking of databases
  and computational resources by means of metadata,
  ontologies and reasoning over both i.e. Semantic
  Web and Grid technologies.
• "Correlate the new molecular structure with the
  existing structural databases what are the
  likely physical properties of the crystal?"
• "Retrieve align 2000nt 5' from every
  serine/threonine kinase in Fabacae expressed
  exclusively in the root cortex whose expression
  increases 5x or more upon infection by Rhizobium
  but is not affected by osmotic or heavy-metal
  stresses is lt40 homologous in the active site
  to kinases known to be involved in cell-cycle
  regulation in any other species"
• This RG will provide a forum to track Semantic
  Web community activities and advise the Grid
  community on the application of Semantic Web
  technologies in Grid applications and
  infrastructure, to identify case studies and
  share good practice.

• This RG will provide a forum to track Semantic
  Web community activities and advise the Grid
  community on the application of Semantic Web
  technologies in Grid applications and
  infrastructure, to identify case studies and
  share good practice.

32
Charter Projected Tasks

• Track semantic web activities and inform the Grid
  community on what tools and ideas to use now and
  which to watch
• Provide a forum to discuss and share best
  practice in 'semantic grid' projects
• Create links with other RG and WG to both push
  Semantic Grid expertise and to offer a service of
  expertise. For example, participation in the
  proposed working group on scheduling ontology.
• Operate a community web portal
• Encourage engagement between the Grid and
  Semantic Web communities.

33
Charter - Milestones

• Produce Primer on Semantic Web technologies for
  Grid applications, for dissemination to the GGF
  community.
• Run a mini-workshop on the "Semantic Grid
  Roadmap" to discuss which aspects of Semantic Web
  can be used now in Grid middleware and
  applications, and which should be watched to
  inform what we are doing now. One output of the
  workshop will be a Semantic Grid 'roadmap'
  document for submission to GGF with a view to
  appropriate groups responding with respect to the
  impact of the roadmap on their group.

34
Charter Milestones

• Create a WG on Semantic Grid Services that would
  show that services could be more effectively
  discovered, matched and composed if they had
  semantic descriptions enabled by ontologies.
• Run a mini-workshop on "Practice and Experience
  with the Semantic Grid" to identify and report on
  Semantic Grid case studies (targetGGF10), the
  report to be disseminated to the GGF community.
  The mini-workshop will include activities of
  other groups in this area.
• Review of Semantic Grid activity

Metadata

• Held BoFs at GGF9 and GGF10
• Propose
• we define metadata in this context
• gather requirements in Semantic Grid RG
• produce requirements document?(replaces roadmap
  document?)
• requirements session at next GGF?
• spawn Working Group?
• when do we need to amend charter?

37
Points to discuss

• We can celebrate many achievements, but
• We havent produced a roadmap document. Do we
  want to? If so need to put process in place (as
  with Primer and Workshop)
• We need more engagement with other GGF
  activities, especially with Working Groups. How
  shall we do this?
• What changes do we want to make to the charter?

38

• Discuss ?

39
Primer Outline

• Provide several semi-independent sections that
  cover the basics. Need to address the following
  problems
• Need to provide a general demystification of the
  Semantic Web.
• Need to convince scientists that they would
  benefit.
• Need to explain relevance of Semantic Web to Grid
  and Web Service architects
• This will be done with several semi-independent
  documents and a reading guide. These can be
  written by volunteers in the appropriate area.

40
Sections of the Primer

• Primer For the Impatient
• This is a 10-20 page document that explains
  things in general terms. Scope should be to
  cover all the other components in small but
  reasonable detail and give the reader the overall
  picture.
• FAQ what is an ontology? What is the diff
  between a taxonomy and an ontology? What is
  metadata? What software is good/scales, etc.
  What relationships are there besides isa? Is
  this data or architecture? Whats the difference
  between an ontology and an instance? What is the
  relationship between ontology and types. What
  can you do with RDF that you cant do with XML?
  Can RDF represent Common Information Model (CIM)?
  What is best practice for developing ontologies
  in scientific communities? Where would I find
  examples of ontologies? What is there an
  ontology for math?

41
Primer Sections Continued

• FAQ (as separate section)
• Metadata Representation, Knowledge
  Representation, and Ontologies (Line Pouchard)
• Should cover RDF, RDFS, and OWL variants in some
  detail, with historical(?) material on DAML-OIL.
  Should use examples from physical sciences.
• Distributed Computing for the Semantic Grid
• P2P, Web Service and Resource Oriented
  Architectures, Crawling, etc. Web services meet
  the Semantic Web.
• How does the Semantic Grid compare to distributed
  object systems? What are the use cases of
  semantic data? What are the programming models?
  That is, how do I handle the problems of dirty
  data? How dynamic can the data in the semantic
  grid really be?

42
Primer Sections Continued

• Tool Survey for the Semantic Grid
• Providing an updated list should be an initial
  priority. Include both free and commercial
  tools. This is intended to include only
  downloadable software, distinguishing it from the
  project survey.
• Research Project Surveys for the Semantic Grid
• This is a list of projects large and small, their
  aims and research focus.
• Setting science context chemistry and
  bioinformatics examples
• Case Studies Semantic Grid Applications for
  Science
• This is related to research projects, but is
  intended to focus on science-specific
  applications.
• Semantic Grid Gap Analysis
• What is missing? Should systemically review the
  state of things and identify missing pieces.

43
Meeting Time and Location

• South Pacific Room 3
• 100-215 pm
• Sea Pearl Room
• 300-400 pm
• Meeting is intended to assemble and develop
  material. Not a tourist meeting, so please come
