Customize Schema Structure

While Bissetii provides a default set of schema, in most cases, you will want to customize them according to your use cases. Here are some of the ways to do it easily.

Customizing Default Schemas

The default schemas are defined in the following pattern and location:

pattern   :          data/bissetii/schema/<type>.toml
directory :    docs/.data/
repo-docs :    docs/.data/bissetii/schema/<type>.toml

Since Bissetii uses data/ directory, all you need to do is to define your own structure and place it in your repo-docs data/ directory with the same relative pathing.

Example, based on the pattern above, if you want to use your own default WebPage.toml, you can create a copy in docs/.data/bissetii/schema/WebPage.toml.

Customizing default schemas will indefinitely affects all the corresponding pages.

Customzing Specific Schema Sources

Starting from Bissetii version v1.13.0, you can place specific schema file anywhere inside your data/ directory. If you do not have any idea, we recommend you to place them inside: data/schema/ pathing for organization purposes.

These schemas can be specific to a page or group of pages based on your page selection.

Selecting A Schema

To select a schema, you feed the selection inside the page’s front-matter as follow:


selectType = "SoftwareApplication"

The value must be of the filename. You can supply your custom schema and specify it inside the selectType. Example:

selectType ValuesTarget
WebPage or defaultdata/bissetii/schema/WebPage.toml

If the schema is not found, Bissetii will fallback to use the default schema (WebPage).

Select Specific Schema Sources

To select a specific custom schema sources, you need to supply the full Hugo compatible data pathing to your schema file. This is done by replacing your data/ and each directory slash with a period (.), and remove the TOML file extension.

Example: here is a schema data file located in the following path:

file locationdocs/.data/schema/LandingPage.toml
data/ directorydocs/.data/
Schema Select Value.schema.LandingPage

Your front-matter will be as the following:


selectType = ".schema.LandingPage"

Building Your Own Schema

To build your very own schema data structure, you MUST to refer to:

  1. Parameters and construct the elements accordingly.

Additionally, to support specific types of parameters for search engine, you can refer to:

  1. Google Search Gallery

Parsing Format

Bissetii uses toml map table to structure the entire parameter schemes. To construct the data structure, you just need to define it accordingly using TOML format.

Dynamic Page Data

Bissetii also allows dynamic value parsing from existing Page data structure using the period (.) notation. Due to Go’s templating limitation, this ability only affects FIRST degree data fields. Anything deeper will be treated as value. Example:

"description" = ".Page.Description" # Will Work : 1st-level (.description)

"description" = ".Page.Description" # WON'T work: 2nd-level (.offer.description)

The data structure (those type NAME struct definition) is available at: Go Meta Component.

Validate Output

Lastly, to validate the generated output, you can use JSON linter website like: Alternatively, for published website, you can test the website output using Google Rich Results Test.
