| - is a next generation internet architecture for data storage, sharing, access and analysis. It is a collection of distributed ecological, biodiversity and environmental data and analytic resources (data, metadata, analytic workflows and processors) possibly at different sites and in different organizations connected by a network and accessed via the internet. |
| + is a next generation internet architecture for data storage, sharing, access and analysis which combines the features of a Data Grid for storage of ecological data and a Compute Grid for analysis and modeling services. It is a collection of distributed ecological, biodiversity and environmental data and analytic resources (data, metadata, analytic workflows and processors) possibly at different sites and in different organizations connected by a network and accessed via the internet. |

| + The EcoGrid will form the underlying framework for data and service discovery, data sharing and access, and analytical service sharing and invocation. Specifically, it will provide: |
| + |
| + **seamless access and manipulation of ecology data and metadata stored at distributed nodes (including scalability, multiplicity of platforms (desktop to super computers) and storage devices); |
| + **authentication through a single sign-on authentication and multi-level access control; |
| + **execution of analytical pipelines via web services (WSFL, and WSDL, XPipe); |
| + **node registry for data and compute nodes based on UDDI; |
| + **rapid incorporation of new data sources as well as decades of legacy ecological data; and |
| + **replication of data to provide fault tolerance, disaster recovery and load balancing |
| + |
| + By extending the expressiveness of service description languages (e.g., WSDL [1], WSFL [2]) for enhancing data and analytical service Grid capabilities the ecogrid will result in an integration of data-, compute-, and service-grids for ecology. |
