Euclid
ST Status : Data Model & EMA mockup
Maurice Poncet (CNES)
on behalf of EC SGS System Team

2. System Team System Team main work packages are :
Architecture & Performance
Monitoring & Control
Processing & Data distribution orchestration
Data Model (J.M. Delouis)
EMA (O.R. Williams)
Data Transfers
Infrastructure Abstraction Layer (IAL)
Common Tools (inc. Collab. Dev. platform)

3. Data Model Definition of I/F between (or inside) pipelines
Defined by OUs pairs (input/output)
From textual description to formal description
(SWG -> OU -> SDC)
Formal description allows for
Unambiguous description
Automation
Validity check
Facilitate S/W development and maintenance
Configuration management
Naming conventions (type, unique id, some semantic info.)

4. Metadata/Data Distinction between : Metadata (data description) Data
XML files (text !)
Structure described by XML Schema
Generic information (type, creator, date, location,…)
Specific information depending on type
Stored at EMA
Data
Format :
FITS files …
Stored at SDCs (+ for prototype where storage is available & accessible)
Data location (e.g. URL) stored at EMA

5. Data Model Status First draft release available (dictionary)
Formal description
basic types (dictionary, should be in line with system product tree)
Interfaces (TBD based on dictionary)
Configuration management under SVN (RSSD)
Model tree (one custodian per leaf)
Release, Work, Archive
CCB (Change Control Board)
One delegate per OU/SDC, EMA, PO+ WP Lead
Next in September
Working groups on hot topics

Catalog description (N. Apostolakos)
Instrument Model (E. Jullo)

Location of data (either SDC, or lab, …)

8. For SIM prototypes Contribute to the data model Register the products
Textual description
Formal description (one custodian per OU/SDC pair)
Register the products
Generate metadata for products
Submit them to EMA mockup for ingestion
Use the EMA mockup to retrieve data
