AstroGrid Project
Report to AstroGrid Oversight Committee
AGOC(2) July 30th 2002
Paper C : Report of Progress against Goals
(C1) Introduction
This report concentrates on progress against the goals stated in the April
2001 proposal, but also describes the development of our final Phase
B goals, milestones, and deliverables. During the course of Phase-A
certain revisions were made to the goals
and milestones for the year - these are noted where applicable.
A full glossary of abbreviations used in this document is given at the
end of this Paper C.
(C2) Original Phase-A goals and deliverables.
This section gives a review of the progress towards the goals
outlined in the April 2001 AstroGrid project proposal.
(C2.1) Phase B plan
Phase-A activities have focused on the capture of requirements,
requirements analysis, assessments of relevant technologies, and analysis
of existing capabilities and relevance. In parallel the AstroGrid Architecture
has been developed using a UML methodology. In the final iterations of
this process, the project has identified a suitably scoped set of science
drivers which will define the AstroGrid Phase-B deliverables. It is important
to note that the 'AstroGrid ten' science drivers have been chosen as
they represent a range of topical Astronomy, Solar and STP science cases
of relevance today and in the near future. Thus AstroGrid Phase-B deliverables
will support scientific endeavour in these areas. However, the tools and
capabilities produced by AstroGrid, with this subset of science drivers,
will be more generally applicable across a wide range of astrophysical science
projects, both today and in the future.
The science drivers are described in the individual science cases,
and these in turn are combined to form the AstroGrid Science Requirements
document. This document will be fully prepared by the end of Phase-A
Q4. An analysis has been performed of the AstroGrid science drivers, whereby
activity diagrammes and sequence diagrammes are generated for each case.
This identifies Use Cases that will be required to deliver the capabilities
and functionalities required by the science cases. A range of use
case have been developed in Phase-A (handling generic issues such as 'user
sign on' etc). Further use cases have been constructed where identified
by the science case analysis. The Architecture is being developed to enable
the construction of a generic virtual observatory, with the analysis of
the science cases described above, feeding into the architecture design.
The current draft architectural analysis is listed on the Wiki.
This process is enabling the project to generate the Phase-B plan
which aims to produce a production system. Milestones against which
the progress of the project will be measured are being developed. The
full Phase-B plan will be provided to the next meeting of the Grid Steering
Committee in Oct 2002.
(C2.2) Science Requirements Document
The large list of science cases that were listed on the AstroGrid
VO Wiki site have been scoped to form a subset of 10 Cases for use as
the key AstroGrid science drivers for its Phase-B. The AstroGrid
'10' science cases have been selected as they demand the delivery of a
set of capabilities that will be relevant to aiding scientific output
in these topical science areas.
The ten science areas cover the following areas:
- Discovery of High Redshift Quasars (Astronomy: involves
optical and near-IR data sets)
- Locating galaxy clusters at a range of redshifts. This will
be linked to predictions from model data. (Astronomy: Models)
- Brown Dwarf selections (Astronomy: involves optical and
near-IR data sets)
- Deep Field Surveys (Astronomy: involves linking radio
with other data on deep fields such as the HDF).
- Low Surface Brightness galaxy discovery (Astronomy: optical,
ear-IR, radio, X-ray)
- Supernova galaxy environments (Astronomy: Optical)
- Solar Stellar Flare Comparison (Astronomy, Solar: linking
understanding of solar flares with those seen in stellar events)
- Solar Coronal Waves (Solar: unravelling this phenomenon)
- STP Solar Event Coincidence (STP and Solar, links solar data
with STP data in understanding space weather)
- Magnetic storm onsets (STP, involves federation of in-situ
and remote sensing data)
The science drivers encompass a wide cross section of areas, and
include drivers aiming to bridge subject area gaps; thus there is a driver
bringing together Astronomy and Solar studies, whilst another links
the Solar and STP domains. Importantly, the capabilities demanded by
these drivers are seen as being of use more generally in the support of
other areas of astronomy. The ten key science drivers have been
selected to enable the project to be scoped to ensure that a Virtual
Observatory capability is generated by the end of the Phase-B period.
The ten science cases are being collated into the overall 'AstroGrid
Science Requirements' document. This will be finalised as a Phase-A deliverable
by the end of September 2002.
(C2.3) Functional Requirements Document
The AstroGrid architecture formulation is, together with
its emphasis on the derivation of use cases from the science drivers,
replacing the formal development of a FRD. The status of the development
of the Architecture for the purposes of Phase-B is described above in
sections C2.1 and C2.2 and is scheduled for completion by September 2002.
(C2.4) Functionality Market Survey Report
There has been no market survey as such. However a number
of key enabling technologies and areas have been identified as crucial
to the development of the AstroGrid Phase-B product. These areas have
been studied in depth and reports prepared.
(C2.4.1) Identity, Authorisation and Authentication (IAA)
Current astronomical facilities on the WWW support anonymous access to
public-domain resources with very limited work flows. To meet even
current aspirations, the Virtual Observatory needs to operate extensive
work flows that also include access to restricted resources. Phase-A's
use case analysis and survey of requirements has shown a need for a pervasive
infrastructure for identifying users and controlling access to facilities
and data. A system has been designed, based on a sophisticated
analysis, which will support the AstroGrid enabled work flows. It
has been derived by the means of the analysis of a wide range of access
and control use cases. The preliminary design for the implementation will
involve the use of the Globus project's Community Authorisation Service
(CAS), but suitably adapted for use by AstroGrid and the VO community. Full
details are listed on the Wiki. The evolving analysis and system design
is described in Rixon (2002) and Rixon et al (2002).
(C2.4.2) The Use of Data Warehouses
An analysis of the use of 'Data Warehouses' as applied to
advanced database federations and manipulations has been carried out.
A detailed paper describing this work has been prepared (Page, 2002).
The application of the MySpace concept to provide individualised data
warehouses has also been considered. This study has formed the basis used
in specifying the PC farm which is being purchased by the end of Phase-B
for use as the prototype AstroGrid Data Warehouse platform.
(C2.4.3) Interoperability - the development of VOTable
The VOTable interoperability standard has been developed
as a collaboration between AVO, NVO, AstroGrid and a number of major
astronomical archive centres. Version 1 of the standard was released
in the form of a DTD and XML standard 15 April 2002. (Details are available
at http://vizier.u-strasbg.fr/doc/VOTable.) Version 1.0 supports
the description and interchange of tabular data only. Extensions of VOTable
to encompass image data files are envisaged, with CDS (Strasbourg) taking
the lead role. AstroGrid will contribute in the context of the Interoperability
work area in the AVO.
(C2.5) Agreed division of labour with international partners
There has been considerable progress in the area of AstroGrid's
relationships with external partners, both in the Astronomy and Grid
technology realms. The collaborations with the AVO and EGSO involving
transfer of funds/staff are noted in this section. Details of other collaborations
are noted in section 2.
(C2.5.1) Astrophysical Virtual Observatory
AstroGrid is formally a member of the Astrophysical Virtual
Observatory (AVO). The 'matching fund' workpackage effort has been aligned
so that a corresponding number of staff years of PPARC-funded effort
count as contributing to the AVO. There are two AVO funded positions
within AstroGrid. These two posts are located at the IfA, Edinburgh.
The positions have been offered to two candidates, final negotiations
are in progress. A third post was located at Jodrell through it's individual
participation within the AVO. This position has been filled and the post
is well integrated within the AstroGrid/AVO project structure.
(C2.5.2) European Grid of Solar Observations.
As reported at the April 2002 AOC, Astrogrid funds the EGSO
coordinator. EGSO in turn have funded replacement effort in the form
of a developer located at MSSL. (In the period before EGSO funding was
available this effort was provided by MSSL.) The partnership between AstroGrid
and EGSO is continuing to crystallise, to the benefit of both partners
and the UK Solar community. It is anticipated that EGSO staff located
at MSSL in the coming two years will interact closely with AstroGrid team
members there.
(C2.6) Working data grid: demonstration of multi-site browsing and
database searching
In the restructuring of the Phase-A objectives, no prototype
data grid was developed. As noted elsewhere the Phase-A has concentrated
on developing an architecture to deliver the capabilities required from
an analysis of the Science Drivers. As noted in the April 2002
AOC submission, AstroGrid did develop a simple data portal to demonstrate
multi-site browsing. The AstroGrid portal demonstrator was one
of six national e-science projects highlighted at the April 25, 2002,
official opening of the NeSC.
(C2.7) Pilot programme data base federations.
The Phase-A pilot programme was constructed with the prime
aim being to learn technical lessons in achieving the data federations
using currently available technologies and capabilities. The Pilot
programme will complete end Aug 2002 with the 'radio', 'solar' and
'stp' pilots proceeding to completion.
The optical/ir/x-ray federation pilots were halted at an
intermediate point. It became apparent that key systems required were
either becoming unsupported (e.g. the 'Objectivity DBMS'
that was in use to service the proposed SDSS EDR/SuperCosmos Sky Survey
federation) or of limited interest for further investigation (O2 in
use in the XMM X-ray database). Therefore lessons from these pilot federations
were noted and the pilots terminated.
Full reports from the Pilot studies are noted on the Wiki
pages. A summary of progress in this area was given by Mann et al (2002).
(C2.8) Pilot visualisation tool and Preliminary database management
system
Development of prototype visualisation and database management
tools was removed as a Phase-A deliverable in July 2001. The AstroGrid
architectural analysis has identified the requirement for the development
of a user portal and client sub-system in Phase-B. Appropriate visualisation
capabilities will be incorporated in this portal/client area. It is anticipated
that existing
visualisation tools will be adapted for use in the Phase-B
AstroGrid system where possible.
The Phase-A AstroGrid system analysis identified no requirement
for the use of a specific database system in Phase-A. Therefore no DBMS
tools were developed or deployed. in Phase-B it is anticipated that
the AstroGrid system will interact with both internally (the Database
Warehouse system) and externally (e.g. archive centre systems).managed
DB's.
(C3) External Relations
AstroGrid is interacting with a wide range of groups, from
the Astronomy and eScience worlds, from the UK, Europe and the USA. The
contacts and relationships that it is forming are beginning to yield tangible
gains for the project as it gains access to additional sources of help
and expertise. At the same time, AstroGrid is feeding back valuable information
and requirements to these groups, important for their development processes.
It is likely that AstroGrid will in its Phase-B be able to transfer techniques
and capabilities that it has developed to projects outside of Astronomy
which are facing similar sets of challenges.
(C3.1) International Virtual Observatory Alliance (IVOA).
Astrogrid is a founder/member of the IVOA. This alliance
is composed of representatives from the major (i.e. AstroGrid, AVO,
the US National Virtual Observatory (NVO)) and all other major and currently
funded virtual observatory initiatives (i.e. eAstronomy Australia, Canadian
Virtual Observatory, German Virtual Observatory, Russian Virtual Observatory,
Virtual Observatory India). The IVOA has a remit of promoting global virtual
observatory initiatives by, in the first instance, ensuring the implementation
of common and agreed infrastructure standards across the constituent projects.
The IVOA has issued a road map which shows the deployment of steadily
increasing capabilities in the next three year time frame.
The Chair of the IVOA is Bob Hanisch (NVO), Deputy Chair: Peter
Quinn (AVO), Technical Chair: Roy Williams (NVO), and Secretary: Nic
Walton (AstroGrid).
(C3.2) eVPAS
eVPAS was formerly constituted as an approved PPARC supported
eScience project at the beginning of 2002. From this point, AstroGrid's
'VISTA' phase-A workpackage (WP-A6) was re-structured to focus on assessing
interface issues between AstroGrid and VISTA data products generated
by eVPAS. A preliminary report on areas where VO demands will impact on
the design of the VISTA pipeline will be prepared as Phase-A deliverable.
(C3.3) UKIDSS and UKIRT/WFCAM
With the slippage of the VISTA project to Q4 2006, the importance
of the IR data sets from the WFCAM camera, and in particular the UKIDSS
public survey programme, has been heightened. AstroGrid has opened discussions
with the teams at CASU and WFAU designing the WFCAM science pipeline.
Mike Irwin (CASU) gave a presentation at the MSSL AstroGrid June 2002
project meeting on the WFCAM pipeline. The demands of WFCAM are seem
to be similar to those of VISTA, albeit with reduced (x4) date rates
due to the smaller IR camera array.
(C3.4) SpaceGrid
Chris Perry, on the AstroGrid team at RAL, is also a member
of ESA's SpaceGrid project. This ESA commissioned pilot study is determining
the feasibility of large scale 'grid' based capabilities to support
ESA's science and technology in the area of Space Science and Satellites.
(C3.5) GRIDSTART
AstroGrid is involved in the Europe wide Grid coordination
programme through its membership of the AVO. Guy Rixon has represented
AstroGrid and the AVO at a recent meeting of GRIDSTART. This meeting
was the 'kick-off' meeting and aimed to encourage cooperation and sharing
of best practise across the various major EU funded 'Grid' projects.
GRIDSTART appears to offer an interesting discussion forum whereby
issues can be discussed and solutions proposed for eventual agreement
at standards bodies such as GGF and W3C. Further GRIDSTART offers the opportunity
for the projects to interact at a one-to-one level. AstroGrid/AVO will
be represented at the second July 25 GRIDSTART meeting.
(C3.6) iAstro
Fionn Murtagh is chair of the COST Action, iAstro, and liases back to AstroGrid.
Possible collaborative iAstro/AstroGrid initiatives such as focussed workshops
are being investigated.
(C3.7) OGSA-DAI
AstroGrid and the bioinformatics eScience project, MyGrid,
have been assigned as 'early adopters' of the UK's core eScience OGSA-DAI
programme. The OGSA-DAI team (project manager Rob Baxter located at Edinburgh's
EPCC) have met with members of the AstroGrid project to discuss the
requirements of the astronomy community. These have been input into
their requirements capture process. AstroGrid are currently in contact
with the IBM development team working on the OGSA-DAI project. It is
expected that AstroGrid will shortly gain access to alpha product releases
supporting distributed, grid enabled, access to the XML XIndice database.
Future releases will support access to main RDBMS such as DB2, Oracle
9i, SQLServer, Postgress, etc.
At this point it is not clear if the development timescale
for the OGSA-DAI team will be well matched for the purposes of AstroGrid
Phase-B development. The OGSA-DAI product releases have been stalled
due to issues concerning the terms of the OGSA-DAI collaboration, and
the exact form of the open source licence under which the products will
be released. At the GGF5 it has been stated that the licence issue will
be resolved shortly, thus AstroGrid can expect to gain access to first
alpha product releases by Aug 2002.
(C3.8) eDIKT
This is generic eScience initiative funded by the Scottish
Higher Education Funding Council. eDIKT will provide a research and
development capability centred on the NeSC with the aim to
create a centre of applied computer science expertise in Scotland.
eDIKT have identified a number of application areas where
significant input from eDIKT might be appropriate. One of these is AstroGrid,
an assessment of where best to deploy eDIKT effort is currently underway.
(C3.9) GridPP
Links have been further cemented with the GridPP project team.
Members from both projects have spoken at each others collaboration
or project meetings. At a technical level a number of key AstroGrid and
GridPP technical staff met at UCL to discuss practical areas of concern.
AstroGrid is closely following the use of the Spitfire database access
system and will be assessing the 'web services' alpha release shortly.
(C3.10) MyGrid
AstroGrid has opened connections with the MyGrid project. The MyGrid
project manager was invited to, and gave a presentation at, the June
2002, MSSL AstroGrid project meeting. It was agreed that further contacts
would be made. Both projects were able to identify areas of common concern,
including database interface issues, ontologies, and intermediate data
storage capabilities.
(C3.11) Regional eScience Centres
AstroGrid is forming links at the regional UK level with
the regional eScience Centres. For instance, Andy Lawrence and Bob
Mann have formed close links with the Scottish eScience initiatives
operating through the NeSC (as described above with eDIKT). Nic Walton
is a member of the Cambridge eScience Centre's management board. Fionn
Murtagh interacts closely with the Belfast eScience Centre.
(C3.12) Core eScience Teams
AstroGrid have fed into the GNT's questionnaire and requirements
capture of application projects expected network needs. The AstroGrid
PM has attended a meeting with the GSC and the GNT to discuss support
and network issues. AstroGrid is making use of the CA at CLRC in issuing
certificates.
(C4) Additional Milestones
(C4.1) Project Architecture
The full project architecture that will be employed to ensure
the delivery of the AstroGrid Phase-A deliverables is currently in its
final stages of development with completion due by Sept 2002.
The current architecture is available on the Wiki at http://wiki.astrogrid.org/bin/view/Astrogrid/ArchitectureDocs
As described in C2.2 the project has selected a set of science drivers.
These have been analysed in detail, each decomposed to determine use cases
required by the scinece driver. Sequence and activity diagrammes have been
constructed.
(C4.2) Development of the Vision Document
The Vision Document will outline and describe the AstroGrid
project, objectives and key deliverables. This document is now rapidly
evolving, an outline has been set out. The Vision paper will be delivered
by the end of Phase-A of the project.
(C4.3) Phase A Pilot technology trials
A small number of technology trials are in progress in Q3/Q4 of Phase-A.
(C4.3.1) Registry/Workflow using Ontology Demo.
This will produce a subset of astronomy ontology and produce
a registry prototype using ontology. Technologies employed include
JBoss (an EJB server), Jena (a JAVA API for reading DAML+OIL documents)
and OilEd (and editor for producing DAML+OIL documents).
(C4.3.2) IAA/CAS demo
Details of this are given above in section C2.4.1.
We have installed the pre-alpha version of CAS (Community Authorisation
Server) from Globus and got it working. A report is available on the wiki
(http://wiki.astrogrid.org/bin/view/Astrogrid/AssessmentOfCAS).
(C4.3.3) Use of the OGSA-DAI project deliverables
Details of this are described in C3.6
above.
(C4.4) AstroGrid Publications and Conference Activity
A full list of the publications that AstroGrid have published
in the academic press is given below in C.A1. Likewise scientific meetings
that AstroGrid members have attended and/or made presentations at are
also listed in C.A2.
(C5) Development of Phase-B Goals, Milestones and Deliverables
This section of the report lists the goals and deliverables that
will form the outputs of the Phase-B of the AstroGrid project.
The original deliverables listed in the original AstroGrid April
2001 paper are noted. New and altered deliverables are indicated with
cross reference made to the descriptions of the Phase-B work areas in Paper
D, Section 5.
(C5.1) Original April 2001 Phase-B goals and deliverables.
The originally proposed Phase-B deliverables were outlined in the
April 2001 AstroGrid submission. The Phase-A study described in these
AGOC(2) papers has lead to an alteration of a number of these milestones.
However, the majority of the original milestones will be addressed at some
level. These are discussed in the following sections with reference made
to the Phase-B goals that have been developed as outlines in Paper D, Phase-B
plan, section D5.
(C5.1.1) A working datagrid for key databases
A major consideration for the AstroGrid project is that it develops
a Phase-B product that enhances the UK communities access to major datasets
originating in the UK, or of import to the UK community. The emerging
Phase-B plan is based upon the AstroGrid 'ten' science drivers as noted
earlier. These cases do require the use of many of the major UK sourced
data sets. These include providing access to:
- optical data held in Edinburgh and Cambridge (e.g. SuperCosmos
sky survey data, ING/CASU Wide Field Survey Data)
- near IR data, e..g. INT CIRSI data in Cambridge (now), and
WFCAM UKIDSS public survey data in Edinburgh (from end 2003)
- X-Ray data, e.g. XMM survey data held in Leicester
- Radio data, e.g. Merlin and later eMerlin data held at Manchester
- Solar data, e.g. SOHO data obtainable from MSSL, and later
Solar-B data
- STP data, e.g. the Cluster data held at RAL
It should be noted that data from VISTA is not explicitly addressed
in the Phase-B plan for AstroGrid. VISTA is now unlikely to start producing
data until early 2007, this well outside the AstroGrid Phase-B timescale.
However, support for WFCAM data is fully included. WFCAM generates data
flow at the level of ~25% of those anticipated from VISTA and thus can
be considered an intermediate challenge in terms of VISTA. The scoping
of the capabilities developed and deployed to support access to WFCAM
data is framed such that they are scalable for VISTA data rates when this
facility comes on line. Thus AstroGrid Phase-B products will be 'VISTA
ready'.
By the end of the Phase-B plan generation (September 2002), specific
desirable outcomes will be listed for each of the science cases. Thus
for instance, in the case of the high redshift quasars case, an outcome
might be for the deployment of a capability to cross federate catalogue
source data, derived from two remotely located data centres, within a
set (and quick) time period.
These goals are thus under development, with an aim for challenging
yet realist targets to be set.
The Phase-B plan includes areas relating to the delivery of the
associated storage and high-throughput datamining machines that will be
required in support of the datagrid.
(C5.1.2) A uniform archive query and data mining interface to support
the datagrid
- simple public query interface by standard web page
- advanced query and datamining interface using supplied s/w
environment
- on line help system (AstroGrid wizard)
These areas will be addressed with activity areas in D.4 Data Federations.
(C5.1.3) Ability to browse simultaneously multiple datasets
- agreed data, metadata, and annotation standards for subsets
of above databases
- agreed WCS
- visualisation tools for examining observation catalogues,
images, source catalogues, spectra etc
Metadata issues will be encompassed in a number of activity
areas, with visualisation in activity area D5.7.1
(C5.1.4) Tools for integrated on-line analysis of data (images and spectra)
- on the fly imaging from UV data
- measuring fluxes, astrometry, curve fitting
Activity area D5.7
(C5.1.5) Tools for on-line database analysis
- high speed whole database queries via indexing, caching and
parallelism
- database subset exploration tools - parameter plotting, rotating,
statistics etc
- whole database manipulation tools - eg. FFT's etc
Activity area D5.3, D5.4 and D5.5 for advanced data mining.
Tools in area D5.7.2
(C5.1.6) Ability for user to upload code to run own algorithms
- new algorithms
- user supplied modelling techniques
Area D5.7.2
(C5.1.7) Tools for database ingestion
- linking private data sets
- procedures for future public database ingestion
Area D5.3 and D5.4
(C5.1.8) Tools for open ended resource discovery
- proposals for protocols/interfaces
Area D5.2
