The structure of an RD

The structure of an RD

A Resource Descriptor(RD) is composed by four main blocks:

• resource metadata
• table
• data
• service

Inside the RD, they layout roughly like below:

<resource schema="theSchema">

    <!-- Define the high-level information describing the resource -->
    <meta name="someField">...</meta>
    <meta name="otherField">...</meta>
    ...
    <meta name="...">...</meta>

    <!-- Define the structure of the internal table -->
    <table id="whatTable">
            ...
    </table>

    <!-- Define how data get ingested and mapped to table -->
    <data id="whichData>
            ...
    </data>

    <!-- Define the interfaces to access the exposed table/data -->
    <service id="someService">
            ...
    </service>

</resource>
