| Identifier | Name | Acceptable values | Description |
|---|---|---|---|
"isStruct" |
Structure | Logical. | If the value is "true" - this class is a structure and can be used in other classes in atributes of a special kind - "Structure [16]". |
"key" |
Key attributes | Array of strings, at least one value. | Specify a key field that uniquely identifies the object in the collection. |
"semantic" |
Semantic attributes | String. | Sets the semantics - the rule of forming the row view for this class. |
"name" |
System name | String only the latin characters with no spaces. | Sets the first part of the name of the meta class file, the system name. |
"abstract" |
Criteria of abstraction for class | Logical | Used only for parent (base) classes. |
"version" |
Version | String. | Allows to set the versioning of the meta to operate the data created in different meta versions in the same collection. |
"caption" |
Logical name | String | The class name displayed in the UI. |
"ancestor" |
Inheritance | Null or string. | A set of attributes, created in the class is inherited by successor classes. It is a way to reduce the number of entities when it is possible to use the same set of attributes. All classes-heirs will inherit the attribute set of the parent + you can make attributes belonging individually to this class-heir (if necessary). |
"container" |
Container attribute | Null or row. | Select the reference attribute that will be used to automatically build hierarchical navigation. The object to which the selected attribute will refer will be perceived by the environment as a container of the domain class instance, and automatically builds a hierarchy of objects. |
"creationTracker" |
Time tag of created objects | String. | Allows to save data/time of the object creation, requires the presence of the corresponding class attribute, the name of which is entered into this field. |
"changeTracker" |
Time tag of committed changes | String. | Allows to save data/time of the object change, requires the presence of the corresponding class attribute, the name of which is entered into this field. |
"creatorTracker" |
Tag of the user who created the object | String. | Allows to save the name of the user who created the object, requires the presence of the corresponding class attribute, the name of which is entered into this field. |
"editorTracker" |
Tag of the user who changed the object | String. | Allows to save the name of the user who changed the object, requires the presence of the corresponding class attribute, the name of which is entered into this field. |
"history" |
Data image | 0 - none | Stores the images of data |
| 1 - arbitrarily | |||
| 2 - up to an hour | |||
| 3 - up to a day | |||
| 4 - up to a week | |||
| 5 - up to a month | |||
| 6 - up to a year | |||
"journaling" |
Journaling the changes | Logical. | Enable / Disable journaling changes of the class objects. |
"compositeIndexes" |
Indexation | Null or array of objects. | Allows you to specify the requirements for the unique combination of fields. |
"properties" |
Attributes | Array of objects. | Array of attribute properties. Each object is described in accordance with the attribute part of the meta class. |
