Ensuring data accuracy and real-time updates in government visualizations with DITA is crucial for providing trustworthy and up-to-date information to the public and decision-makers. There are conventions and best practices that government agencies can follow to achieve this.

Data Accuracy

One convention is to establish data accuracy guidelines and validation processes. This includes regular data quality assessments and data cleansing to identify and rectify inaccuracies. When using DITA for documentation, structured data sources should undergo thorough validation to ensure they provide accurate information. Here’s an example of how data accuracy can be addressed:

<topic id="population_data">
  <title>Population Data</title>
  <data src="https://gov-agency.gov/population.json" />
  <accuracy-checks>
    <check type="data-validation" />
    <check type="source-authenticity" />
  </accuracy-checks>
  <content>...
</topic>

In this example, the <data> element references a JSON data source containing population data. The <accuracy-checks> section specifies checks for data validation and source authenticity, ensuring the accuracy of the data.

Real-Time Updates

For real-time updates, government agencies can implement automatic data retrieval and synchronization mechanisms. DITA documentation can include elements that specify data refresh intervals, ensuring that visualizations are regularly updated. Here’s an example:

<chart type="line" data-ref="population_data" refresh-interval="1 hour" />

In this example, a line chart references the “population_data” source and specifies a refresh interval of one hour. This ensures that the chart always reflects the latest population data.
