EcoGrid in SEEK

ANAYSIS & MODELING LAYER

SEMANTIC MEDIATION LAYER

DATA/COMPUTE LAYER


Aims of ecogrid

Aims of EcoGrid

Which, Where, How, Who ????

Share Data and Information

Relate Data from multiple projects/groups

Crosswalks across data structures

Develop Eco-related Finding Aids for Data

Global User: Authenticate and Authorize

Provide an infrastructure for “Archivable Collection-building” for SEEK scientists

Facilitate the A&M layer and the SMS layer


Challenges of ecogrid

Challenges of EcoGrid

Data & User Diversity

6000+ datasets & 1500+ scientists

themes, methods, units,structures

Small data sizes but high complexity - metadata

Multiple Data Organizations

Biodiversity Surveys

Population data

GIS, Satellite Images, Weather Data, …

Ontologies & Taxonomies

Data Discovery: No single place to find

Data Entropy – rapid decline of information on data

Autonomy with Centralized access

Leverage Computational Grid work


Our charge

Our Charge

Develop a framework for “global access to ecologically-related data”

Look at current approaches, existing systems & grids

List features/functionalities we want to see in EcoGrid

Study how to leverage, integrate, extend existing work

Come up with architectural framework & user interfaces

Identify Datasets that should be in the EcoGrid

Identify Networks that will be part of the EcoGrid

Identify Methods that can be used through the EcoGrid

Identify people, members, partners

Identify timeline, goals, milestones


Existing services

Existing services

Metacat – syntactic and semantic metadata querying/inserting/updating/deleting, user registration/authentication, data replication, data/metadata versioning, - supports any XML-based metadata

Xanthoria – common-schema mediator (currently 8 sites) metadata query/insert/update/delete for any XML schema to underlying metadatabase (SQL, native XML)


Existing systems

Existing Systems

Prometheus – querying classification taxonomy, query/describe graph structures

DiGIR – querying arbitrary XML-describable resources (underlying data sources can be any type: RDB, XMLDB).

ClimDB – integrating (using wrapping at the data source) diverse format climate data. Access through web, common schema identified beforehand – tabular description

HyperLTER – summary ontology as metadata for images put in as metadata, image extraction /geographicsubsetting/band-level subsetting/ - integration with MODIS images and Hyperspectral images, TM images, airphotos, …


Existing systems1

Existing Systems

Veg Bank – 3 databases co-occurrence records, species taxonomic database that is concept-driven, community classification. Distributed vegbank, querying by plots. Querying/insert/update/annotate across three diverse databases that are described using XML

SRB – access distributed data, syntactic, semantics,user-defined (arbitrary relational) metadata based querying. Annotations for data. Opertions on data. Extraction of metadata. ingest,bulk ingest, delete,upate of data/metadata


What is needed for data ecogrid

What is needed for Data/EcoGrid

Define definitions for structures for data that will be processed in SEEK data grid

Vectors, graphs, tables, trees, ….

Extend EML to take account of DDI and other metadata standards

List a set of services that might be supported by data

Identify common languages and mappings for a structural vocabulary

Ex. Occurrence, co-occurrence, as key words

Identify the services of EcoGrid Components

Identify Registry Language – users/data/methods/resources/srorage/compute
