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 ECHO file search Rapid Response GCMD keyword search Directed Infusion User Reg ACCESS Infusion Subsetter Reuse/Repurpose/Integrate Content Outreach SIPS ESDSWG Community ESDIS 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 Others GeoRSS EMS VizTool(s) 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. KML • 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 DAAC • 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
