| | 298 | The association type format is analog to the [[#TopicType|Topic Type]] format: |
| | 299 | |
| | 300 | ||= Property =||= Description =||= Format =|| |
| | 301 | || `id` |||| ''See [[#Topic|Topic]]'' || |
| | 302 | || `uri` || A globally unique identifier. Every association type has an URI. || A string of format <domain>.<project>.<name> || |
| | 303 | || `type_uri` || Fixed. || `"dm4.core.assoc_type"` || |
| | 304 | || `value` || The association type's name. Readable by human. || An arbitrary string. Can contain spaces and special characters. || |
| | 305 | || `composite` || Fixed. || {} || |
| | 306 | || `data_type_uri` || The association type's data type. That is the data type of one instance's payload.\\\\`dm4.core.composite` denotes a complex association type which is composed of child types. The other 4 data types denote a simple association type. || One of these 5 strings:\\\\`"dm4.core.text"`\\`"dm4.core.number"`\\`"dm4.core.boolean"`\\`"dm4.core.html"`\\`"dm4.core.composite"` || |
| | 307 | || `index_mode_uris` || For simple association types: Controls how the association instance's payload is indexed. Default is no indexing.\\\\For complex association types: not used. || An array with zero or more of these strings:\\\\`"dm4.core.off"`\\`"dm4.core.key"`\\`"dm4.core.fulltext"`\\`"dm4.core.fulltext_key"`\\\\See [[#IndexModes|Index Modes]] || |
| | 308 | || `assoc_defs` || For complex association types: a list of child type definitions. Each definition references a child type and provides further declarations, e.g. cardinalities.\\\\For simple association types: not used. || An array of child type definitions.\\\\See [[#AssociationDefinition|Association Definition]]^1)^ || |
| | 309 | || `view_config_topics` || View models for various clients. || An array of view configuration topics.\\\\See [[#ViewConfiguration|View Configuration]] || |

| | 311 | ^1)^ ''Association Definition'' is a legacy term but still reflected by the property name. It should be renamed to ''Child Type Definition''. The respective property should be renamed to ''child_type_defs''. |
