-===== Vocabulary ===== 
- 
-The VOCABULARY table includes a list of the vocabularies collected from various sources or created de novo by the OMOP community. This reference table is populated with a single record for each vocabulary source and includes a descriptive name and other associated attributes for the vocabulary. ​ 
- 
-The record with vocabulary_id = 0 is reserved to contain information regarding the current version of the Entire Standardized Vocabularies. 
- 
-^Field^Required^Type^Description^ 
-|vocabulary_id|Yes|varchar(20)|A unique identifier for each vocabulary, such as ICD9CM, SNOMED, Visit.| 
-|vocabulary_name|Yes|varchar(255)|The name describing the vocabulary, for example "​International Classification of Diseases, Ninth Revision, Clinical Modification,​ Volume 1 and 2 (NCHS)"​ etc.| 
-|vocabulary_reference|Yes|varchar(255)|External reference to documentation or available download of the about the vocabulary.| 
-|vocabulary_version|Yes|varchar(255)|Version of the vocabulary as indicated in the source.| 
-|vocabulary_concept_id|Yes|integer|A foreign key that refers to a standard concept identifier in the CONCEPT table for the vocabulary the VOCABULARY record belongs to.| 
- 
-==== Conventions ==== 
- 
-  * There is one record for each Vocabulary. One Vocabulary source or vendor can issue several Vocabularies,​ each of them creating their own record in the VOCABULARY table. However, the choice of whether a Vocabulary contains Concepts of different Concept Classes, or when these different classes constitute separate Vocabularies cannot precisely be decided based on the definition of what constitutes a Vocabulary. For example, the ICD-9 Volume 1 and 2 codes (ICD9CM, containing predominantly conditions and some procedures and observations) and the ICD-9 Volume 3 codes (ICD9Proc, containing predominantly procedures) are realized as two different vocabularies. On the other hand, SNOMED-CT codes of the class Condition and those of the class Procedure are part of one and the same Vocabulary. 
-  * The vocabulary_id field contains an alphanumerical identifier, that can also be used as the abbreviation of the Vocabulary name. 
-  * The vocabulary_name field contains the full official name of the Vocabulary, as well as the source or vendor in parenthesis. 
-  * Each Vocabulary has an entry in the Concept table, which is recorded in the vocabulary_concept_id field. This is for purposes of creating a closed Information Model, where all entities in the OMOP CDM are covered by a unique Concept. 
-  * In past versions of the VOCABULARY table, the vocabulary_id used to be a numerical value. A conversion table between these old and new IDs is given below:
