9.9.3.1. Main Objectives¶

The main purpose of this recipe is:

To embed Schema.org markup in a web page that publishes multiple datasets in a single page.

9.9.3.4. Method¶

We will outline the steps for marking up a page in your site that is about multiple datasets. The resulting markup will be compliant with both Google’s Dataset markup guidelines and the Bioschemas DataCatalog Profile.

We will use FAIRsharing as an example for this recipe which makes three datasets available within its markup.

Identify the page in your site about a specific dataset, e.g. https://fairsharing.org/
Open the Bioschemas Generator
1. Select DataCatalog from the Bioschemas Profile dropdown
2. Enter the URL of the page in URL box, e.g. https://fairsharing.org/
3. Click on the Show Form button

Complete the profile form with the information relevant for your page. Once completed, click on the Generate Markup button
- You should complete all Minimum properties and as many Recommended properties as possible. You can show/hide properties using the Additional Properties buttons.
- Where possible you should link to other resources. The Bioschemas Generator does not make this as simple as it could, but you can do it in step 5 once you have generated your markup, e.g. our dataset will link to a page with DataCatalog markup in rather than repeating all the properties for now we will just enter a url and no other properties.
  - If there are separate pages for your datasets then you should link to them using an @id link
  - Otherwise you can include the markup within the DataCatalog markup
- The form defaults to the data type with the first alphabetical character, e.g. for identifier this defaults to PropertyValue but Text or URL will be more appropriate in most cases
- The right side of the screen gives examples for properties, where these have been provided by the Bioschemas profile authors. Click on the Show button to see the example for a specific property. Click on Minimum, Recommended, or Optional to expand/contract the section and see the properties contained at that marginality level

You will now see the generated markup in JSON-LD format. You can click on the Microdata and RDFa tabs to see the same content rendered in the different formats. However, we recommend the use of JSON-LD. For our FAIRsharing.org example, we get the following markup

Download or copy and paste the generated markup

Make adjustments for any bits that could not be properly entered through the form.

For example, for our generated markup we would change the provider so that it provides a direct link rather than repeating the properties. We would replace

"provider": [
    {
      "@context": "http://schema.org",
      "@type": "Organization",
      "dct:conformsTo": "https://bioschemas.org/profiles/Organization/0.2-DRAFT-2019_07_19",
      "description": "",
      "name": "FAIRsharing.org Registry"
    }
  ],

with

"provider": [
    {
      "@type": "Organization",
      "@id": "https://fairsharing.org/communities"
    }
  ],

You can test that your JSON-LD is valid syntax, and visualise your markup using the JSON-LD Playground.

Once you are happy with your markup, include the JSON-LD, script tags and all, at the bottom of your HTML page template. Make sure that this is before the closing </html> tag

Your site should now include DataCatalog markup.

Once you have deployed this on your web server, you can test it with the Bioschemas Validator which scrapes the markup from your page and allows you to test it against various Bioschemas profiles¹.
