  1. 3rd SeaDataNet training course – Ostende – 16-19 June 2008 MIKADO tool M. Fichaut, V. Tosello, M. Larour

  2. Overview • Objectives, background and technical characteristics • Mikado main features • Differences between MIKADO V0 and V1 • Manual input of metadata • Use of the common SDN vocabularies • Automatic XML generation • Connection to the local database • Query writing • Mapping to the local database • Practical work session

  3. Objective • MIKADO is used to generate XML catalogue descriptions, it creates XML ISO-19115 files using SDN common vocabularies for metadata exchange of • CSR - Cruise Summary Reports • EDMED - Marine Environmental Data sets • CDI - Common Data Index • EDMERP - Marine Environmental Research Projects • [EDIOS – Permanent Ocean-observing System] • To use MIKADO you must be familiar with the XML documentation of SDN which can be downloaded from BSCW : SDN Technical Task Team ISO Application of ISO 19115 within SeaDataNet V1 XML METADATA for CSR V1 ….

  4. Some background • Mikado version 0 • created for the SEA-SEARCH project • used for SeaDataNet V0 • Mikado version 1 • New version of Mikado to be compliant with the SeaDataNet V1 XML schemas, and the SeaDataNet common vocabularies • Completely rewritten, more user friendly

  5. Technical characteristics • Written in Java Language (Version >= 1.6) • Available under multiple environments : • Microsoft : Windows 2000, XP, VISTA • APPLE • Unix - Solaris • Linux • Use of the 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 Mikado works offline once the list are up-to-date

  6. MIKADO main features (1) • MIKADO can be used in 2 different ways • One manual way, to input manually information for the catalogues and CDI in order to generate XML files. • One automatic way, to generate XML descriptions automatically, from information catalogued in a relational database. Automatic way is needed for those who have many entries referenced in a relational database • Only one interface for all catalogues • Same look • Same principles

  7. CSR EDMED EDMERP CDI [EDIOS] Manual XML files for SeaDataNet catalogues MIKADO Java code Automatic DATABASE JDBC Java DataBase Connectivity EXCEL File Native Drivers MYSQL ORACLE POSTGRES SQLServer Bridge Drivers using Microsoft ODBC (ACCESS, EXCEL, SQL SERVER) Other Drivers Downloaded from ad hoc Websites (Copied in the dist/lib MIKADO directory) MIKADO main features (2)

  8. Differences between V0 and V1 • No need to modify configuration files with JDBC connections and SQL queries • database connection and the user the queries are save as XML files • EDMERP catalogue available in MIKADO • Manual Input of data • Input screens updated to be compliant with the new XML schemas • List of values = common vocabularies • Automatic generation of XML files : more interactive and user-friendly • Help for JDBC connection – connection checking • Help for the SQL query writing – query checking and query saving • Incremental mapping with the local database

  9. MIKADO – Manual input

  10. MIKADO – Manual input • Available for 4 catalogues : EDMED, CSR, CDI, EDMERP • EDIOS will be also available in the near future • Each input generates an XML file that can be sent to the central catalogues • For EDMERP and CSR : EDMERP CMS and CSR online can also be used, but MIKADO is useful • if you have problems with the NETWORK connection • if you want to keep locally an XML description of your catalogues • For EDMED and CDI, there is no online input tools.

  11. MIKADO and vocabulary lists

  12. Automatic check of the version of the vocabulary lists : once when MIKADO starts MIKADO downloads locally the latest version of each list Possible to enable-disable the automatic check and download of the lists and to work offline MIKADO and vocabulary lists

  13. MIKADO manual – vocabulary lists (1) • Common vocabulary BODC, • list C320 (Country ISO codes)

  14. MIKADO manual – vocabulary lists (2)

  15. MIKADO – Automatic XML generation

  16. MIKADO automatic - connexion • Help for the connexion to the database • Pre-filled information for some databases • Check the connexion

  17. MIKADO automatic – connexion OK

  18. MIKADO – automatic – connexion KO

  19. MIKADO automatic – queries • Expendable tree • Main query Return the ID • Single queries Return 1 row • Multiple queries Return 1 to n rows

  20. MIKADO automatic – queries • Write the queries • SQL syntax (for Oracle, Excel, MySQL, …) and SQL variables must be adapted to your own data base • Check the Queries • Green OK • Red KO : read the error message

  21. MIKADO automatic – single queries • All the XML variables are listed in the expendable tree • In bold : mandatory fields • 1 to n single subquery can be written • In green : fields already fulfilled • Add or to detele variables in a query • Check the query

  22. MIKADO automatic – multiple queries • All the XML variables are listed in the expendable tree • Number of queries is pre-defined • The list of variables for each of these multiple queries is also pre-defined • In bold : mandatory field • In green : fields already fulfilled

  23. MIKADO automatic – multiple queries • In a group of variables (same XML block, same pre-defined set of variable in a query), the non mandatory variables can be left to null

  24. MIKADO automatic - Save the queries • When all the queries are written • They can be saved in an XML file to be re-used later on

  25. MIKADO automatic - generate the XML files • Select the catalogue you want to generate • Open the corresponding queries • Choose the output directory • Export the XML files • Progress bar • Cancel allowed

  26. MIKADO automatic - local mapping • While generating the XML files for all the catalogues • Each time that MIKADO does not recognized a value (entrykey or entryterm) which should come from the common vocabulary, it asks the user for mapping • MIKADO manages a demand-driven continuous (incremental) extension of a local mapping : mapping of the local database to the common vocabulary • Mapping tables can be modified • Delete rows • Modify the LOCAL value

  27. MIKADO automatic - local mapping • Example • CSR generation • Mapping of the platform type

  28. MIKADO automatic - local mapping • Modification of the local mapping • If wrong entries have been input, it is possible to: • Delete one entry • Delete all the entries • Change the local code

  29. MIKADO – User manual • User manual is provided : • in : SDN_tools\Mikado_usermanual • File : SDN_MIKADO_UserManual_v1.pdf • Detailed explanations for MIKADO use, lots of snapshots

  30. MIKADO helpdesk • When using MIKADO • Questions and errors must be reported to sdn-userdesk@ifremer.fr • Subject of the mail should be : • MIKADO question or • MIKADO error

  31. Practical work – to-morrow • Manual input of one EDMED form • Manual input of one Cruise Summary Report • Automatic generation of CDI files • One dataset of 81 XBT SIPPICAN files • EXCEL or MySQL • Use the XML validator to see if your files are valid • Copy MIKADO material on your own computer • Copy the directory SDN_TOOLS.zip file and unzip it

  32. Practical work – requirements Make sure that the java version is > = 1.6 • To know if Java is available on your computer, in the right version, follow these steps : - Open 'Start' menu, then 'Execute' - On the displayed window, enter: 'cmd', then click on 'OK' button - Enter 'java -version' • Check if command has been executed : - If not, download the last java version at http://java.com/en/download/index.jsp. - Else, check the version displayed. The version should be greater than or equal to 1.6.

  33. Practical work – requirements • For the trainees who want to test Mikado with MySQL • Those who have already MySQL on their labtops : make sure that MySQL Query Browser is also available. • If not, you must install it by double clicking on the following file from the common directory SDN_tools\databases\mysql\install\Query_browser\ file : mysql-gui-tools-5.0-r12-win32.msi • Those who do not have MySQL: let us know, we will install it on your notebook.
