Node.js DCAT Metadata Parser

This Node.js script parses DCAT metadata serialized in Turtle (TTL) format and generates an HTML report containing information about a specified dataset and its distributions.

Usage

1. Ensure you have Node.js installed on your system. You can download it from here.

2. Clone or download the repository to your local machine.

3. Install the required dependencies by running the following command in the terminal:

   npm install
   

4. Run the script with the following command:

   node dcat-to-htmltable.js <metadataFilePath> <datasetSubjectURI>
   

   Replace <metadataFilePath> with the path to the metadata TTL file and <datasetSubjectURI> with the URI of the dataset subject you want to extract information about.

5. The script will generate an HTML file named dataset_info.html containing the dataset information and distributions.

Example

Suppose your metadata.ttl file is located in the parent directory and you want to extract information about the dataset with the URI https://www.unitedutilities.com/corporate/responsibility/environment/natural-environment/bowland-winep/. You would run the following command:

node dcat-to-htmltable.js ../metadata.ttl https://www.unitedutilities.com/corporate/responsibility/environment/natural-environment/bowland-winep/

The script will then generate the dataset_info.html file containing the dataset information and distributions.

Additional Features

Microdata Integration: The HTML output includes microdata annotations, making the content more machine-readable. Microdata attributes are added to the HTML tables, allowing search engines and other applications to better understand the structured data.
