## WHAT IS A SIS?

**Software Interface Specification**
**Describes the archive pipeline and interface to PDS**
**Cassini-Huygens Program requirement**
**Mars Exploration Program requirement**
**Although a SIS has not been a PDS requirement in the past, it is rapidly becoming a defacto PDS requirement and it is a “darn good idea”**

## WHY A SIS?

**Historically PDS has been reactive.  HQ did not include archiving requirements in AO’s and archiving was done when the “money was gone”. With the current HQ management we are working in a proactive environment.**
**There is increasing demand for early data release in cost-capped missions. This requires the establishment of a data pipeline that allows efficient data access and archiving. **
**Ideally the SIS should define the pipeline structure that will also serve team access to the data.  The archive products should be picked off the pipeline that the team is using.  This will be assure they are more “scientifically usable”.**

## WHY A SIS?(Cont.)

**ESA is under pressure from member countries to provide data access.  They are implementing similar procedures. **
**Jean-Pierre Lebreton and Joe Zender are working to assure this development is parallel to the PDS.**
**Joe resided at the Small Bodies Discipline node at the Univ. of Maryland to develop the Rosetta data base and is currently working with the Huygens team.**
**Joe Zender has developed a template for an ESA Planetary Science Archive Interface Control Document. It defines the data pipeline and WE LIKE IT! **

## THE HUYGENS “SIS”

**The Huygens instrument teams will use the ESA Planetary Science Archive Interface Control Document (SIS/ESAICD) template.**
**The ESAICD template will be reviewed in the November Huygens Data Archive Working Group telecon.**
**It has been proposed that teams generate drafts by the January PSG meeting.**
**A Design Review is contemplated to assure that when the ESAICDs are completed they will define the data pipeline for each instrument. **

## HQ AWARENESS OF THE NEED FOR SIS’s

**The first paragraph of the Science Requirements Section, of the latest Mars Scout AO, states: **
**“ **Mars Scout investigations are intended to complement and potentially amplify the otherwise established NASA Mars Exploration Program (see Section 2.2 above)........  **Mars Scout investigation teams will be responsible for initial calibration, validation, and analysis of the data, its subsequent delivery to the NASA Planetary Data System (PDS) in calibrated format (i.e., with adequate documentation), and the timely publication of initial scientific results. “**

## DATA TRACKING

**Development of an archive delivery and ingestion tracking system is underway.  This system should allow you to determine the state and location of all data submitted to the PDS. **
**D. Conner Has been working directly with PDS developers to assure that this system will serve the CASSINI/HUYGENS team.**** **

## MINIMAL REQUIREMENTS

- The minimum Cassini science data archive is defined as:
-    Uncalibrated data full resolution data
-    Calibration files
-    Algorithms or documented source code to apply
-       calibration data, along with complete documentation
-       describing the process
-    Sample calibrated data files for future users to verify
-       their calibration application
-    Metadata as specified by PDS Standards
