ECHO Systems

The ECHO project manages three publically visible systems:

  • Operations - The live 24x7 Operational ECHO system allowing discovery of datasets, granules, and services made available by the EOSDIS data centers.
  • Partner Test - A test system running the same ECHO version as the Operational system or preview version of the next major ECHO version facilitating beta testing by current ECHO partners.
  • Alpha Testbed - A test system running the latest development release of the next major ECHO version facilitating alpha testing by current ECHO partners.

ECHO Operations

The ECHO Operational system is a production system which serves the needs of the Earth Science community. The Data Holdings within this system include those which ECHO's Data Partners have made available for use by the Earth Science community.

Resources

 The following resources are available for the ECHO Operational system:

Support

The ECHO Operational system is supported by the ECHO Operations Team, in conjunction with the ECHO Database, Development, and System Administration teams. Automatic monitoring systems are used to continually monitor the Operational system. Any system failures will result in an immediate notification to the ECHO Team and elicit an immediate response. Questions regarding the Operational system should be sent to echo @ echo.nasa.gov and a member of the ECHO Operational team will assist in your needs.

Ingest Guidelines

The ECHO Operational system continually ingests submitted metadata files to keep its holdings up to date with the holdings of each Data Partner. The ECHO Operations team works with each Data Partner's data management group in order to discuss changes in metadata submission rates or rejections which occur during ingest. All questions specifically regarding ingest should be directed to the ECHO Operations Team (echo-ingest @ echo.nasa.gov).

Discovery Guidelines

The ECHO Operational system contains data holdings which are made available through the efforts of both Data Partners and the ECHO Team. Access restrictions for data are managed solely by the corresponding data partners. These rules are subject to change according to the policies of the owning Data Partner.

Data discovery is achieved completely within the ECHO system and, subsequently, performance is linked to the system load at any given time. The ECHO team is continually monitoring the performance of the system and improving internal querying methods. ECHO Client Partners are encouraged to utilize the 'best practices' outlined within the "Client Partners" portion of this website. All questions regarding data discovery should be directed to the ECHO Operations team (echo @ echo.nasa.gov) for support.

Ordering Guidelines

The ECHO Operational system contains data which is available online or through numerous delivery methods (ftp pull, dvd, etc...) Each Operational Data Provider configures their data and order policies within ECHO to facilitate requests for data. All orders placed in the Operational mode will be submitted directly to the appropriate Data Partners for fulfillment. Unless prior arrangements are made, all submitted orders will be treated as a real request for data.

Once an order has been successfully submitted, the orderer can expect to be contacted by the Data Partners who are fulfilling the order. If ECHO is unable to successfully submit the order, the orderer can expect to be contacted by ECHO. Once communication has been made by a Data Partner, specific questions regarding the order should be directed to that data center's user services group.


Beta Partner Test

The ECHO Operational system is a test system which serves the needs of the ECHO Data, Client, and Service partners. The Data Holdings within this system include those which ECHO's Data Partners have made available for their own testing purposes

The following resources are available for the ECHO Partner Test system:

Support

The ECHO Partner Test system is supported by the ECHO Operations Team, in conjunction with the ECHO Database, Development, and System Administration teams. Automatic monitoring systems are used to continually monitor the Partner Test system. Any system failures will result in an immediate notification to the ECHO Team. Because this system is not a 'production' system, failures will be attended to during normal working hours. Questions regarding the Operational system should be sent to echo @ echo.nasa.gov and a member of the ECHO Operational team will assist in your needs.

Ingest Guidelines

The ECHO Partner Test system ingests submitted metadata files to meet the needs of Data Partner testing activities. The ECHO Operations team is continually working with Data Partners to test and improve the metadata generation and ingest processes. All questions specifically regarding ingest should be directed to the ECHO Operations Team (echo-ingest @ echo.nasa.gov).

Discovery Guidelines

The ECHO Partner Test system contains data holdings which are made available through the efforts of both Data Partners and the ECHO Team. Access restrictions for data are managed solely by the corresponding data partners. These rules are subject to change according to the policies of the owning Data Partner.

Data discovery is achieved completely within the ECHO system and, subsequently, performance is linked to the system load at any given time. The Partner Test system is not a performance system and therefore response times are not indicative of Operational response times. Due to the nature of the testing environment, data accessibility is subject to change based upon Data Partner testing. All questions regarding data discovery should be directed to the ECHO Operations team (echo @ echo.nasa.gov) for support.

Ordering Guidelines

The ECHO Partner Test system contains data which has been ingested to facilitate testing by ECHO Data and Client Partners. Each Data Provider configures their data and order policies within ECHO to facilitate their own testing needs. All orders placed in the Partner Test mode should be coordinated with the associated Data Partner who will be fulfilling the order. Due to the nature of this test system, orders may or may not be fulfilled, based upon the needs of the requester. All questions regarding ordering should be directed to the ECHO Operations team (echo @ echo.nasa.gov) for support.


Alpha Testbed

An Alpha Testbed has been established in order to facilitate an exchange of ideas and provide early insight into the upcoming capabilities offered by ECHO.

ECHO is a set of infrastructure services that allow the publication, discovery and access to resources that support the Earth Observation community. Those resources may include information resources (data collections, inventories of data granules and browse images), service resources (using Web Service technologies) and client resources.

The capabilities offered in this testbed are based on the most recent internal release of ECHO. These capabilities allow organizations to experiment with offering their capabilities as services and leveraging ECHO in new and innovative ways. To that end, this testbed supports all ECHO capabilities, including API methods and metadata ingest.

In support of the ECHO functionality, a number of resources are being made available to participants. These include:

  • User Documentation of APIs
  • User Documentation on Web Service interfaces
  • Sample code for Java and C#
  • GUI applications for Registration and management of Services
  • Service Taxonomy Navigation Tool
  • Limited set of test data (science datasets and granules)

Because this is a testbed, there are a few differences between this and the operational version of ECHO. Those differences are largely in "quality of service". For example, the version of the operational software is "alpha", in particular the web service interface are new and not operationally verified and are subject to change without notice. Also, the testbed is not supported as a 24x7 Operational system. Both the Operations and Development teams support the testbed participants - in addition to their other primary responsibilities.

If you are interested in participating in the ECHO Alpha Testbed program, you must apply by submitting a description of your work as it relates to the Earth Observation community, your goals for participating and must fill out and sign the ECHO Alpha Testbed Memorandum of Understanding (MOU). You may download that MOU here.

Once filled out and signed, please apply by sending an email to echo @ echo.nasa.gov, including a description of your work, your goals and attach a scanned copy of the signed MOU.

Thank you for your interest.
