A customizable data catalog for users of the EDI Data Repository
ezCatalog is based on the PASTA-JavaScript-Search-Client developed by Tim Whiteaker for the Long-Term Ecological Research Network (LTER).
Researchers and organizations publishing data in the EDI Repository may wish to create a searchable data catalog on their website. This project includes code supporting such functionality.
- Fork this GitHub repository.
- Once the repository is forked, go to Actions and enable GitHub Actions for your repository. This is security requirement imposed by GitHub on forked repositories that include GitHub Action workflows.
- Initialize GitHub Pages for your fork. Go to Settings > Pages and select Source to be "Deploy from a branch" and Branch to be
/rootof the main branch. - Construct a filter query to identify your data in the EDI Repository and to be listed in your catalog using one of the following options:
- Unique Keyword - A unique keyword identifying your research group and published in the metadata of each of your EDI data packages can be used as a filter. For example, the research lab of Cayelan Carey publishes data with the keyword "Carey Lab" and the filter query
'&fq=keyword:"Carey Lab"'returns all their data. - Data Package Identifiers - A list of data package identifiers in the form id:scope.identifier. For example,
'&q=id:edi.23+id:edi.101+id:edi.845'returns the newest versions of data packages:edi.23,edi.101, andedi.845. - Scope - For LTER only. The scope identifying your LTER site. For example,
'&fq=scope:knb-lter-cap'returns all data of the Central Arizona-Phoenix LTER.
- Unique Keyword - A unique keyword identifying your research group and published in the metadata of each of your EDI data packages can be used as a filter. For example, the research lab of Cayelan Carey publishes data with the keyword "Carey Lab" and the filter query
- Add the filter query to
config.txtand commit the changes. - Use GitHub Actions to build your catalog with the build_catalog workflow. Go to Actions and under Workflows select Build catalog, then Run workflow. Wait for the workflow to complete, then click the Live demo page to see your catalog (it may take a few minutes to update). Subsequent pushes to your fork will automatically rerun the
build_catalogworkflow. - Copy the HTML snippet below and paste it into the body of your webpage. This will reference the catalog hosted on GitHub Pages from within your website.

To see an example of how to embed the catalog in a web page <iframe>, view the page source code of the Jornada Basin LTER Data Catalog or experiment using the W3Schools HTML Tryit editor.
Note: If you decide to rename your fork of ezCatalog, you will need to update both the iframe code snippet and live demo hyperlink with the new repository name.
Autocomplete is currently supported for the creator and taxonomy input fields. Try typing a couple of characters into the creator box of the demo page and see what happens.
Autocomplete requires creating a list of possible choices, which is automatically generated each time the GitHub Actions workflow build_catalog runs.
ezCatalog allows you to limit the number of results returned per page. If you do not wish to use pagination, set the limit parameter in config.txt to a number higher than the number of datasets available for your group.
The success of search queries depends upon the metadata provided when submitting data to the EDI Data Repository.
Please contact support@edirepository.org for help setting up your catalog or resolving issues.
ezCatalog is a basic data catalog. If interested in developing a more feature rich catalog, we recommend checking out the video on Using the PASTA+ Search API to Create a Local Data Catalog.
