Space properties are defined in the homepage of a space in the document properties table. To distinguish space properties from document properties there is a naming convention:

1. Document Property Names start with a capital letter and are human readable. That is they may contain spaces, e.g. "My Document Property".
2. Space Property Names start with a lower case letter and are tokens. That is they are separated by dashes, e.g "my-space-property".
3. Break convention number 2 if you specify a value from your domain as a space property.
