Objectives of med2medsdn
Objectives of Med2MedSDN

  • Translate MEDATLAS files to SeaDataNet MEDATLAS files - available under Windows

    • Version 1.1.02 and user manual available at :

http://www.seadatanet.org/standards_software/software/Med2MedSDN


Med2medsdn main features
Med2MedSDN main features

  • Reformats MEDATLAS files to MEDATLAS SeaDataNet format

    • Java tool, bilingual (French, English)

    • Adds the additional SeaDataNet information : mapping for parameters and LOCAL_CDI_ID and EDMO_CODE

    • Can reformat one file or a large number of files (in one directory)

    • Generates a coupling file for the SeaDataNet download manager

    • Linked to SeaDataNet vocabularies through Web services for parameters mapping and for list of EDMO codes

      • Need of internet connexion while updating lists

Objectives
Objectives

  • NEMOis a reformatting software used to

    generate ASCII files at MEDATLAS or ODV formats which are defined as SeaDataNet formats for data exchange between SeaDataNet partners. Can be downloaded from SeaDataNet Web site :

    http://www.seadatanet.org/standards_software/software/nemo

  • It was created in IFREMER for internal purposes, and adapted to take into account the SeaDataNet formats and vocabularies.


Technical characteristics
Technical characteristics

  • Written in Java Language (Version >= 1.6)

  • Bilingual (French, English)

  • Available under multiple environments :

    • Microsoft : Windows 2000, XP, VISTA , APPLE

    • Unix - Solaris

    • Linux

  • Use of SeaDataNet common vocabularies web services

    • to update lists of values of the SeaDataNet common vocabularies

      • need network connections in order to have up to date lists of values.

      • But NEMO works offline once the lists are up-to-date


  • Reformat any ASCII file of vertical profiles, time-series or trajectories to a SeaDataNet ASCII format (ODV, MEDATLAS).

    • The input ASCII files can be :

      • one file per station for vertical profiles or time series

      • one file for one cruise for vertical profiles, time series or trajectories

  • Interact with Mikado, to be able to generate ISO-19115 XML descriptions of the data.


Nemo principles
NEMO principles

  • NEMO must be able to read almost any ASCII format to translate it to MEDATLAS, ODV

  • Users of NEMO describe the entry files format so that NEMO is able to find the information which is necessary in the SeaDataNet formats

  • One mandatory pre-requirement is that in the set of entry files the information about the stations must

    • be located at the same position : same line in the file, same position on the line or same column if CSV format

    • be in the same format

    • For example : for all the stations the latitude is

      • on line 3 on the station header,

      • from character 21 to character 27, or 3rd column in CSV

      • the format is +DD.ddd


Running nemo
Running NEMO

  • 4 or 5 steps to convert the entry files to a SeaDataNet format

    • Describe the type of file(s)

    • [Describe the cruise, if the files are related to 1 cruise]

      • NEMO is able to read XML CSR generated with MIKADO

    • Describe the station information

    • Describe the measured parameters

    • Convert the file

  • One more step to

    • Save the description of the format (Model)


  • Nemo description of entry files 1
    NEMO - Description of entry files (1)

    • Where are the files?

    • Is it a cruise?

      • Is it one file per cruise or one file per station ?

    • Is it a collection of station files ?

      • grouped by cruises or not?

    • Are the files with separators?

      • Tabulations? Semicolon? Comma?

    • Are they vertical profiles, time series or trajectories data?


    Nemo description of entry files 2
    NEMO - Description of entry files (2)

    • File to convert is displayed in NEMO window

    • The principle is to describe the input file by selecting the information in the file window




    Cruise description

    • Can be

    • Manually input

    • Imported from a SeaDataNet XML CSR

    • Imported from a database (IFREMER only)

    • NEMO is able to

    • Generate a SeaDataNet CDI Summary

      • Text file containing the minimum mandatory information needed in the CDI ISO-19115 description

      • This file can be converted to an Excel file

      • Which can be read by MIKADO to generate the XML CDI files

    • Generate a coupling table that will be used by the Download manager of SeaDataNet

      • It is the link between the LOCAL_CDI_ID and the file

    • If the “Generate mapping” option is clicked :

    • NEMO will insert a record in the coupling table for each vertical profile, time series or trajectory that it converts.

    • The coupling table is managed by a local database imbedded in NEMO

    • The coupling table can be :

      • Edited (for modification, insertion or deletion)

      • exported (to be used by the download manager)

      • imported (from previous version of NEMO, for example)
