displayInfo and displayAttribute Tags

Description​

This feature allows you to display global attributes of your choice on the datasets page in the Information row.

Usage Instructions​

These tags can only be used with the Sax parser. To enable and use them, follow these steps:

  1. Enable the SAX Parser: Add the following line to your setup.xml file:

    <useSaxParser>true</useSaxParser>

  2. Add Tags in datasets.xml: In the datasets.xml file, include two top-level tags:

    <displayInfo></displayInfo>
    <displayAttribute></displayAttribute>

  3. Default Behavior:

    • If these tags are not added or left empty in the datasets.xml file, the default values are applied as follows:
      • displayInfo: Summary,License
      • displayAttribute: summary,license

  4. Ensure Consistency: The number of comma-separated values in both displayInfo and displayAttribute tags must be the same.

How It Works​

  • The displayAttribute tag specifies global attributes (defined within the <addAttributes> tag) to be displayed for each dataset.
  • The corresponding values in the displayInfo tag are displayed as labels in the Information row of the UI.
  • When the user hovers over the displayed labels, a tooltip will appear, showing the value of the global attribute.

Example​

<displayInfo>Display1,Display2</displayInfo>
<displayAttribute>att1,att2</displayAttribute>

Dataset Global Attributes Example:​

<att name="att1">This is att1</att>
<att name="att2">This is att2</att>

UI Behavior:​

  • The words Display1 and Display2 will be displayed in the Information row on the UI.
  • When hovered, tooltips will display the corresponding attribute values:
    • Display1: Tooltip shows This is att1
    • Display2: Tooltip shows This is att2

Notes​

  • Ensure the attribute names specified in the displayAttribute tag match the global attributes defined in the dataset.
  • Incorrect or missing attributes will log error messages.

By following these steps, you can customize the Information row on the datasets page to display relevant global attributes with corresponding tooltips.
