Background latest activities and information systems in japan l.jpg
Background - Latest activities and information systems in Japan

  • Improvement of services

    • Earthquake Early Warning System

    • Very detailed warnings for individual municipalities

  • Rapid progress in information and communications technology

  • Roles of various media and the use of their characteristics


Jma s ongoing project to develop xml format for warnings and advisories l.jpg
JMA’s ongoing project to develop XML format Japan for warnings and advisories

  • Project goals

    • Format conversion: from various forms of conventional text to a unified and comprehensive format

    • Uniform format: for information on various natural disasters from observations to forecasts

    • Flexible format: computer-processable form allowing the addition of new elements for future services

    • Availability to users: a generally accepted system is cost-effective in the long run

  • Project collaborators

    • Technical support from the XML Consortium on XML standardization

    • Coordination with governmental organizations and the mass media


Already operational cap is cap applicable to jma s project l.jpg
Already-operational CAP: Is CAP applicable to JMA’s project?

  • Comparison of JMA’s project and CAP

    • Purpose: Distribution of disaster prevention information

    • Target: All natural hazards (other than human-induced accidents)

    • Content: User requirements for information; compartmentalization and quantification

  • possible by JMA with CAP

    • The essence of JMA’s warnings is expressible with CAP; torrential rain, flooding, storm surges, earthquakes and volcanic eruptions

    • Very detailed observations and forecasts cannot be expressed with CAP; quantitative estimates and time-sequential values

  • Characteristics and key points of JMA’s XML format

    • A data dictionary derived by analysis and restructuring of conventional information elements

    • Automatic development of an XML schema from the data dictionary

  • Structure of JMA’s XML format

    • Three elements: control part, head part (similar to CAP) and body part (quantitative expression part for each area of meteorology, seismology, volcanology)

    • Reusable basic elements in every part: atmospheric temperature, pressure, magnitude, etc.

    • Extensibility; allows new elements to be added in the future

  • Issues discussed in development

    • Data type for physical values in basic elements: float type (not string type)How can invalid values and missing data be described in XML?

    • Management of XML schema: name spacing and version numberHow can forward and backward compatibility between schema and instance be maintained?

  • Applications of JMA’s XML format

    • Computer-processable structure:Various values can be stored from plain text to code values, i.e., binary data

    • Processable with user applicationse.g., Prefectures: outlook for the entire area Municipalities: detailed analysis in individual areas

In the future l.jpg
In the future II

  • Consider specific applications for CAP in Japan

  • Easy creation of XML code in CAP format from JMA’s data dictionary

  • Data dictionary will be a big asset to JMA’s introduction of XML
