Earth Science Collaboratory: A rich data analysis environment that:
• Provides access across a wide spectrum of Earth Science data, analysis tools + services
• Supports collaboration on and sharing
of data, tools, results and knowledge
Islands of data and services with selective connectivity

• Based on
– data access standards
– common data model
– semantic matching of
tools, data and workflows
• Discovery
– data, tools, workflows, experiments
– search by keyword, variable, time,
space, author...
• Information Mgmt
– provenance
– identifiers
– archive
• Semantic Web
– data and tools ontology
• Cloud
– provisioned storage + computing
NASA HQ Site
– DAAC web sites and services still exist, but use the same high-level navigation, nomenclature and
other functionalities so users are familiar when they arrive.
Content Management System
Application Server Middleware
Utilize EOSDIS-Wide Services
– An active and immersive user experience leveraging existing and future Web Services (e.g. W*S,
SOAP, RESTful) into a seamless package – search, subset, visualize and deliver data in one session
with one username and password while invoking multiple remotely hosted tools
– Cloud capable

LANCE
Web Services
• Fresh and continually updated and coordinated content
Phase 1
•Uniform Navigation
•Full exposure for Web Services
•Cross-DAAC web content search
Phase 2
•Web Service Chaining
•Social network features
•Harmonize nomenclature

Phasing:
Invoke DAAC Specific Services
DAAC
• More than just a website or portal
External Sites
Earth Observer, Climate,
USGS, NOAA...
EOSDIS WEB SITE
DAAC
We must preserve what we currently
do very well
– Users navigate the system without needing to know how/who is providing each service.

•
How do we present ourselves as a
coherent system of systems but stay
flexible to integrate new missions and
technologies
• Present EOSDIS as a coherent yet transparent system of systems by leveraging SOAs
provided by DAACs, ECHO, GCMD, EMS, User Reg…. New missions, technology and
partnerships
DAAC
•
Websites are the front door to data
and services for users, but are
currently underutilized and discordant
Goals
OGC W*S
•
NASA Earth Science Data Systems are
a large and continuing investment in
science data management activities

Architectural Concept
An Initial Step: EOSDIS Coherent Web and Information Architecture Evolution
OPeNDAP
Context
DAACs
maintain web sites but
implement CMS so they can
feed content to ESDS site
Phase n
•Widely available standard Web Services
•ISO 19115 et al.
•Transparent user experience
