tags

This polymorphic property is an array of tags (textual labels) associated to the object.
For details on using the different serialization/deserialization styles, refer to the section below "Polymorphic styles"

OData searches

You can use this property as a filter condition in an OData expression via the eq operator and the startswith, endswith functions.

Examples:

  • 'eq' -> GET: /api/{version}/Company/Search?$filter=tags eq 'category'

  • 'startswith' -> GET: /api/{version}/Company/Search?$filter=startswith(tags,'te')

  • 'endswith' -> GET: /api/{version}/Company/Search?$filter=endswith(tags,'ro')

  • Complex example -> GET: /api/{version}/Company/Search?$filter=startswith(tags,'te') or endswith(tags,'ro') &$orderby=id asc&$top=10&$skip=0&$select=id,companyName,billed,tags

Schema

The following table contains the main schema information about this data type.

FeatureValue
Complex typeActivityDTO
Required:

Polymorphic Schema

The polymorphic schema describe how the object is serialized and deserialized by the Web API pipeline.
Some properties are "native", and have a single serialization format.
Some properties are "polymorphic", and can be serialized/deserialized using multiple formats (known as "styles")


Free Fields

This Business Object is customizable, and it is therefore possible to define a set of custom fields.
These custom fields are called Free Fields.

Free Fields are user-definable custom fields, and can contain data of various kinds.

Each Free Field has a specific data type (selected during configuration), and on the basis of this type, the field data follow certain validation rules.

For more details about Free Fields, refer to the appropriate section

Free Field and polymorphism

As with many other fields, Free Fields also implement polymorphic serialization capabilities, and it is therefore possible to select multiple serialization/deserialization styles.
For more details, refer to the specific descriptive paragraph on the serialization of the Free Fields

Free Field and OData

Free Fields can be used in OData searches as field selectors ($select criterion).
In order to be able to discriminate them from the other standard fields of the Business Object, it is necessary to specify the prefix "FF_"

Example:

GET: /api/{version}/{controller}/Search?$select=id,FF_MyCustomFreeField1,FF_AnotherFreeField
