View source for Formatting a CSV for Entities and Associations Import

To bulk import model content, the CSV file should be formatted as described in this article.

{{Info| 1=Each row of the CSV creates one attribute on an element. Creation of new elements is incidental and done only if a match isn't found.}}


== General Column/Data Requirements ==
The following column headers must exist and contain data in each row:
* Element_Name
* Operation_Type
* Attribute_Name
* Attribute_Type

The following columns are optional:
* Element_Description
* Element_Tags
* Attribute_Description
* Attribute_Tags
* Association_Path
* Package_Name
* Package_Description
* Package_Tags

== Column-specific Requirements ==
=== Element Name & Description ===
* If an Entity (or Association) with a matching name is found in the model, the attribute will be added to it.
* New created elements default to a type of Entity.
* If an Entity (or Association) is created, the description is applied to that new element. If the element already exists, its description (if not an empty string) will be updated with the description provided here.

=== Operation Type & Association Path ===
* Must be set to 'Composition' or 'Association'. If Operation_Type is Association, then the Element will automatically be turned into an Association.
* If the Attribute already exists, it will be updated to be an Associated Entity (i.e., turns the Entity into an Association)
* There '''MUST BE AT LEAST TWO''' associated entities or the creation/update operation will fail. It is possible to only add a single associated entity if the element already exists and already contains an associated entity.
* By default, the Association Path is empty. This is an advanced concept used to relate to specific attributes of an element rather than the entire element itself.

=== Attribute Name, Type & Description ===
* Attribute_Name is the desired name for the attribute.
* Attribute_Type must be a valid Observable, Entity, or Association that either 
** exists in the model, or 
** was created on a previous row.
* Attribute_Description is the description that will be applied to that attribute. If the attribute already exists, its description (if not an empty string) will be updated with the description provided here.

=== Package Name & Description ===
* These columns allow you to place new entity in the package specified by Package_Name. If a package with the provided name does not exist, the new package will be created under the PhenomEntities package.
* Package_Name specified the name of the existing/new package.
* Package_Description specifies the description that will be applied to that package.

== Tagging (Optional) ==
* Optional columns can be added in to CSV to tag new Packages, Elements, or Attributes.
* Each field can have multiple comma delimited tags.
