When you need entity-level metadata, you can get it based on Entity ID, Entity Name, or GE Object.

1. Get Entity Metadata when you already have a GE Object. This is a synchronous function that returns the entity metadata.

   Code Block
   // Assumes you already have a variable called 'ge' holding a GE Object. var entityMd = ge.entityMetaData();

2. Get Entity Metadata knowing the Entity Name using Aptify.framework.metaData.entities.loadEntity(). This is an asynchronous function that passes the entity metadata into its callback.

   Code Block
   var entityName = "Persons";   Aptify.framework.metaData.entities.loadEntity(entityName, function (entityMd) { // entityMd contains the entity metadata });

3. Get Entity Metadata knowing the Entity ID using Aptify.framework.metaData.entities.loadEntityById(). This is an asynchronous function that passes the entity metadata into its callback.

   Note
   Because Entity IDs are not reliable cross-database, we don't recommend this as a primary approach. However, when you are in a situation in which some other part of the system has provided the Entity ID, this method is handy.

   Code Block
   var entityId = 1006;   Aptify.framework.metaData.entities.loadEntityById(entityId, function (entityMd) { // entityMd contains the entity metadata });
