2. MMFI Current Status
MultiMission Facility Infrastructure is evolving to accommodate the full set of requirements from existing and future ESA supported missions
Main contract is FEOMI (Facilities Evolution into and Open Multimission Infrastructure), aiming at
defining the new MMFI architecture
porting present mission-specific Envisat, ERS and TPMs ground segments
Phase-1 successfully completed with Preliminary Design Review milestone achievement

5. MMFI and OAIS
With respect to the OAIS reference model, there are conceptually two approaches to analyze the FGS in the context of the ESA mission payload infrastructure:
The FGS can be viewed as one essential part of the whole organization providing an OAIS conformant distributed archive. This is the ADAR approach
The FGS can be itself defined as an OAIS conformant archive that is part of a cluster of federated OAIS archives, where the central infrastructure elements provide federation

6. MMFI and OAIS (2)
The requirements on the responsibilities are applicable to the organization that operates the OAIS archive. The OAIS conforming system shall enable the organization to:
Negotiate for and accept appropriate information from data producers
Obtain sufficient control of the information provided to the level needed to ensure long-term preservation
Determine, either by itself or in conjunction with other parties, which communities should become the designated community and therefore should be able to understand the information provided
Ensure that the information to be preserved is independently understandable to the designated community
Follow documented policies and procedures which ensure that the information is preserved against all reasonable contingencies, and which enable the information to be disseminated as authenticated copies of the original, or as traceable to the original
Make the preserved information available to the designated community
The MMFI enables ESA at the sites to fulfil the requirements 1, 2 and 6. The other requirements have to be fulfilled on organizational level.

14. New Missions and Developments
In line with Oxygen, all new ESA EO missions will rely at various levels on the MMFI architecture and components
GOCE LTA development started, based on present MMFI (pre-FEOMI)
AEOLUS LTA development to be started, architecture now re-baselined to be fully MMFI compliant
SWARM and SMOS full ground segments (Core PDS and LTA) proposed to be fully MMFI-based
GMES Sentinel missions concept. Study ITT published, awaiting for industry proposals. SoW requires MMFI analysis and reuse
New processing systems under development will have MMFI interface (e.g. new Linux-based Envisat processors)

15. HARM (Historical Archive Rationalization and Management)
See presentation given in Toulouse
Analysis of data volume reduction from orbit stitching on-going
Transcription HW&SW from old media (D1, DLT) to AMS (StorageTek T9940B based) started for selected datasets
Transcription of Envisat off-line datasets to be started (~60000 tapes on shelves)
SAFE (Standard Archive Format for Europe) – see later

16. Other activities
PV-2004 proceedings CD-ROM ready to be delivered to participants
Support to PV-2005 organization. Edinburgh, UK – November 2005)
PV-2007 to be hosted by DLR in Oberpfaffenhofen, Germany
…  PV is becoming a regular venue!
Presentation to 19th International CODATA conference in Berlin
MMFI architecture based on OAIS and SAFE based on XFDU presented
Presentation on data compression usage in ESA EO ground segment given to OGC meeting held in Frascati
Interest in collaboration with OGC for upcoming GML/JPEG2000 packaging OGC standard

17. Standard Archive Format for Europe (SAFE)
ESA’s goal is to make SAFE:
Compliant with ISO 14721:2003 OAIS (Open Archival Information System) reference model
Compliant with emerging CCSDS/ISO XFDU (XML Formatted Data Units) packaging format
Designed to act as a standard format for archiving and conveying data within ESA Earth Observation archiving facilities
Although the primarily goal of SAFE, in the framework of the HARM project, is to handle EO data with processing levels close to the usually called “level 0”, no a-priori limitations should exist regarding the packaging of higher level products
