Scope and Assumptions The purpose of this document is to provide common requirements for data archiving, data distribution and user services for EOSDIS-supported data. These services are currently being provided by the Earth Observing System Data and Information System (EOSDIS) Data Centers or Distributed Active Archive Centers (DAACs). Other elements of EOSDIS may also be subject to a limited set of these general requirements. Rather than refer to specific Archive Centers/DAACs, this document refers to an entity providing such services as an Distributed “X Active Archive The data system that provides the functionality to provide Center (XDAAC)”. the services is referred to as an Data System is assumed that the reader is familiar “X (XDS)”. It with Earth Observing System (EOS) Data and Information System (EOSDIS) terminology. The intent of this document is to requirements as opposed to any implied specify “what” implementation or “how”. This document does not include discussion of network requirements and communications systems. Security requirements are covered by pre-existing security plans tracked by the ESDIS Computer Security Officer. Network requirements are discussed in separate documents.
