Why do I need a schema?

Schemas are the building blocks of Hystruct. They define what data is extracted from a website. You can think of a schema as a template for extracting data from a website. In other words, they define what data you’re actually interested in.

​
How do I create a schema?

Creating a schema is easy. You can create a schema by clicking on “Schemas” in the main navigation, and then on the “Create Schema” button in the dashboard.

​
Schema field types

Hystruct supports a variety of field types, including:
  • String (some text)
  • Number
  • Boolean (true or false)
  • Date (a string representing a date)
  • Array (a list of items)

​
Schema field options

Each field type has its own set of options. For example, you can give the field a name, description, a type (see above) and an example.

​
Why should I give a field an example?

Giving a field an example can help our AI extraction engine understand what data you’re interested in. For example, if you have a field called “amount” and you set an example of $10.00, our AI engine will know that you’re looking for a dollar price amount, rather than a quantity.
