PROCESS OVERVIEW

ONE GOAL

BUILD THE RIGHT SOFTWARE

Original Approach

Testbed• Alpha Release every 2

weeks• Open to the public• Early feedback• 20% Dev Time Reserved

for feature request and prioritization

Partner Test (Beta)• Early beta – approx Feb

2011• Open to the public with

WIST announcement• Solicit public input on

Reverb prioritization

Operational• May 2011• Already have a base of users

from beta testing• Smooth (ideally non-existent)

transition from beta testing• Allow for continued

evolution of Reverb

Development Lessons Learned

• Deployment overhead still too high to sustain 2 week alpha pushes– Nuances of new technologies contributed to costly build

process• Feedback focused more on features not-yet

implemented vs. testable functionality• Needed preview release in Partner Test

sooner than later to test end-to-end ordering outside of Ops

• 20% rework was sometimes difficult to plan for, but was very useful to address feedback concerns

• “Top 5” requests were helpful, but under-utilized

Modified Approach

• Monthly alpha release pushes to Testbed• Point releases as needed to meet major

milestones or to address significant bugs• Delayed beta testing until more

functionality was implemented• Plan in 20% rework to each development

sprint for bug fixes & enhancements per feedback

• Continue to request “Top 5”, but start nailing down required bug fixes for major milestones early

BETA RELEASE CHANGED THE DYNAMIC

REVERB IS THE PLATFORM FOR FUTURE ECHO CLIENT INNOVATION

Moving Reverb Forward

• Core Reverb functionality will become part of monthly sustaining activities

• Reverb will become Operational on May 16• Development will continue with monthly

Alpha pushes to Testbed• Reverb Beta will continue to exist and serve

as a prototype space for T2R4 and potential client technology efforts

• Operational Reverb will be updated as part of the normal Operational deployments

Specific functionality will be discussed later today

REVERB SHOWCASE

Dataset Discovery

• First class dataset discovery• Fast keyword filtering of datasets• Ability to add entire datasets to

cart to support dataset download and ordering

• Ability to applyservices directly todatasets

• Temporal and spatialfiltering of datasetswithout doing agranule search

Improved Form Rendering

• Fully styled form rendering• Support for native controls

including spatial selectionareas on maps withmultiple projects

• Inline error and helpinformation

• Smooth form expansionand collapsing to showor hide input areas

• Same rendering engine usedfor Orders and Service invocations

Bulk Download

• Support for bulk download of large number of items

• Supports multiple download options• Text file of URLs to

support wget and curl

• FTP batch download script

Services

• Added dynamic servicediscovery and invocation

• Services can be associated using tags

• Leverages familiar ECHO Forms for service UI presentation to the user

• Can be extended to supportwide variety of APIs (e.g.: GLASSubsetter, ESI)

• User input can be as simple as selecting an area of interest and desired dataset.

Maintainability

• Reverb is based on modern web standards– Ruby on Rails3, HTML(5), CSS, JavaScript

• Fully automated valids, ACLs, and keyword generation

• Follows well established ECHO Development best practices

• Extensive suite of automated tests

Minimized Ops/DAAC Interaction

• Minimized Ops/DAAC Coordination– Reverb reduces the number of items on which ECHO data partners need to

coordinate with the ECHO Operations team.– Reduced coordination simplifies Reverb maintenance.– Data partners can modify Reverb interactions through modifying metadata.

Reverb-Enabled Metadata Cleanup

• Resolved Metadata Inconsistencies & Errors – Missing Collection Temporal Metadata– Missing Collection Spatial Metadata– Incorrectly defined “MODIS Tile” 2D Coordinate System– Invalid NSIDC Descending Crossing Longitude– Archive Center Cleanup

• Identified Metadata Issues– Inconsistent Processing Level Usage– Invalid LARC_ASDC Granule Temporal Values– Conflicting “ASTER” Instrument & Sensor– Invalid OnlineResourceURL MimeTypes– OnlineResource vs OnlineAccessUrl– Non-specific browse file extensions

REVERB AUTOMATION

WIST Valids

• WIST– Valids configured to run once/hour for guest users.

• Metadata or guest user access changes lags according to valids frequency.• Valids runs as a stand alone process, not integrated with WIST.

– Valids processing runs on-demand when a user logs in.• There are no lagging issues having to do with metadata modifications.

– Information Gathered for Dynamic Presentation• Collections available to guest users• Science Keywords• Additional Attributes

– ECHO Operations Configured Information• Data Quality Summaries & Assignments• Radio Button Mappings• 2D Coordinate Systems• Additional Attribute Grouping

Reverb Valids

• Reverb– Valids processing configured to run once/hour for guest users.

• Metadata or guest user access changes will lag in Reverb interface.• The valids process is integrated with Reverb and runs as a core part of the app.

– Valids processing runs on-demand when a user logs in. (No Change)• Valids are refreshed every hour for the registered user.

– Information Gathered for Dynamic Presentation• Search Terms• Platforms & Instruments• Campaigns• Science Keywords• Processing Levels• 2D Coordinate Systems• Calendar Events• Provider Holdings (Granule Counts)• Services (Including Dataset Tags)

Calendar Events

• WIST– Calendar events managed by providers in WIST Interface.– Username/Password not synchronized with ECHO system.– Alerts/Info displayed in scrolling banner & on separate calendar page.

• Reverb– Calendar events managed by providers in PUMP & made available to all ECHO

client partners through SOAP & REST API, or end users via RSS. – All provider and system calendar events loaded from the ECHO system.

• NCR 11010933 tracking issue re: Reverb displaying non-active events– ALERT events displayed in “Availability” section & INFO events displayed in

“Notices” section.– HTML formatting available for improved readability.

• Data Partner Responsibilities– Management of ECHO calendar events belongs to Data Partners.– Continue to update WIST & Reverb to reflect accurate alerts & info events.– Remove non-active events when the end-date has passed.

Data Quality Summaries

• WIST– Configured by ECHO Ops team in cooperation w/ Data Partners.– Displayed when user adds a collection or granule to their cart.– If a registered user has accepted the DQS and the DQS changes, they will not

be presented with the new DQS.• Reverb

– Data quality summaries managed by providers in PUMP & made available to all ECHO client partners through SOAP & REST API.

– Displayed when a user searches for granules within a dataset.– Modified DQS are displayed to registered and guest users.– HTML formatting available for improved readability.

• Data Partner Responsibilities– Management of ECHO data quality summaries belongs to Data Partners.– Update Reverb & coordinate w/ ECHO Ops to accurately configure DQSs.

REVERB TECHNICAL OVERVIEW

Implementation Notes

• Implemented using an Agile Process• Implemented using Ruby on Rails, HTML,

CSS, JavaScript• Mostly built on top of new ECHO REST API

– Remainder will be moved to Multiformat REST API late summer

• Implementation time and team– ~10 months– ~6 developers

Maintainability

@javascriptFeature: Spatial search for datasets In order to narrow my dataset results by spatial bounds as a Reverb user I should be able to visually select boundaries for my dataset searches

Scenario: Type in a valid polygon Given I am on the home page When I select "Polygon" from "spatial_type" within ".spatial-field" And I wait for datasets to load When I fill in "spatial" with "-9.102, 40.430, 22.594, 22.852, -1.406, 1.055" within ".spatial-field" And I wait for datasets to load Then I should find the dataset with id "Dataset with normal cartesian bounding rectangle" And I should find the dataset with id "Dataset with normal cartesian polygon" And I should not find the dataset with id "Dataset with cartesian point”

• Nearly all testing is fully automated• Unit Tests using Test::Unit• Integration Tests using Cucumber,

Capybara, and Celerity

ECHO DBECHO DB

Deployment Model

ECHO Kernel(SOAP API)

ECHO Kernel(SOAP API)

REST API REST API

Reverb Reverb

ECHO DB

Reverb is deployed to

multiple serversUsers are transparently

balanced across instances

Reverb distributes its search and order load

across all ECHO kernels

Reverb takes advantage of ECHO’s ability to distribute

across DB nodes

Like ECHO, Reverb can be updated

without downtime.

Supported Browsers

• Officially supported– Firefox– IE7 and IE8– Safari on OS X

• Unofficially tested– Firefox 4.x– Chrome 11– Safari 5.x

Supported Browse Image Types

• Reverb will automaticallydisplay browser friendly types (JPG, PNG, etc.)

• Reverb can detect HDFbrowse and automatically extract embedded JPGs

• Multiple browse images are support and fetched asynchronously for performance

Supported Spatial Projections

• Searching– Google Maps Mercator– North/South Polar Stereographic

• Subsetting Projections– North/South EASE-Grid (EPSG:3408, EPSG:3409)– Hughes / NSIDC North/South Polar Stereographic

(EPSG:3411, EPSG:3412)• Spatial Extent Visualization (results)

– OpenLayers– Plate Carree (equirectangular)– North/South Polar Stereographic

Spatial extent drawing

• Reverb can render multiple granule spatial extents

• Will provide swath and polar rendering before release

WIST 2 REVERB TRANSITION

WIST To Reverb Migration

• EDG to WIST Recap– Accounts migrated from EDG instances to ECHO requiring user actions.– DAAC USO involvement to notify users encouraging self-migration.– Self-Migration tool developed and made available by ECHO team.– Password reset required during migration

• WIST to Reverb Preparation & Execution– No account migration activities required.– Users may self migrate to Reverb on their own.– WIST & Reverb usage will continue to be monitored.

• Discussion– How should we advertise the Operational Reverb on WIST?– How can we encourage users to self-migrate?– What criteria should be considered for starting a forced migration?– How is the final migration enforced?
