# Data model

This section details the three data models used by P4 Search.

Every data model document has a unique Elasticsearch document ID (_id) in the format <type>-<depotFile>#<rev> except for the ChangeModel, which uses the format <type>-<changeNumber> for its ID.

For example, for an AssetModel document, the ID might be asset-//depot/dam/Music Loops/License.txt#1

You can perform a document look-up on Elasticsearch as follows:

GET http://localhost:9200/index-perforce1-000001/_doc/asset-%2f%2fdepot%2fmain%2fp4-perl%2fP4.pm%2329

The Elasticsearch document ID (_id) cannot be larger than 512 bytes.

## ChangeModel

One instance of the ChangeModel represents a single change in the P4 Server. The following attributes are stored in Elasticsearch:

Name | Description | Type
--- | --- | ---
type | Fixed string "change" | String
change | P4 Server change number | Long
`date` | Change date | Long
client | P4 Server client name | String
`user` | P4 Server user | String
`restricted` | Whether the change is restricted or not | Boolean
`description` | Change description | String
`depotFile` | Depot file path | String

## ContentModel

One instance of the ContentModel represents the contents of a single changed file in the P4 Server. The following attributes are stored in Elasticsearch:

Name | Description | Type
--- | --- | ---
`type` | Fixed string "content" | String
`depotFile` | Depot file path | String
`rev` | P4 Server revision number | Integer
`change` | P4 Server change number | Long
`date` | Change date | Long
`fileName` | File name | String
fileSize | File size in bytes | Long
`fileType` | File type, for example: text, binary, symlink, unicode, utf8, utf16. For more information on file types, see File Types in the P4 CLI Reference | String
`action` | P4 Server action, for example: add and edit | String
`user` | User that submitted the change | String
`contentType` | Content type detected by the Tika library | String
`content` | The content of the file indexed by the Tika library. Includes handwriting or any other text | String

## AssetModel

One instance of the AssetModel represents a P4 DAM asset in the P4 Server. The following attributes are stored in Elasticsearch:

Name | Description | Type
--- | --- | ---
type | Fixed string "asset" | String
depotFile | Depot file path | String
rev | P4 Server revision number | Integer
change | P4 Server change number | Long
date | Change date | Long
fileName | File name | String
fileSize | File size in bytes | Long
digest | MD5sSum of content | String
fileType | File type | String
action | P4 Server action, for example: add and edit | String
user | User that submitted the change | String
blur | The BlurHash for the image | String
blurSize | Blur pixel dimensions based on thumbnail/preview | String
`detected` | Auto-detected image tags. For <TagModel>, see TagModel | List<TagModel>
`attributes` | List of 'key' and 'value' pair of tags | List<AttributeModel>
customAttributes | Array of 'uuid' and 'value' pairs | JsonArray
contentType | Content type detected by the Tika library | String
metadata | Metadata found by the Tika library, for example: EXIF metadata and more | Map<String, String>
gps | GpsModel data extracted from EXIF metadata. See GpsModel | GpsModel

### TagModel

One instance of the TagModel represents a single instance of an auto-detected tag on a file in the P4 Server. The following attributes are stored in Elasticsearch:

Name | Description | Type
--- | --- | ---
`tag` | Tag name | String
`confidence` | Confidence of detection (floating-point value from 0 to 1, where 1 represents 100%) | Float
`positions` | Optional: 1 or more x, y points locating the tag within the image. Stored as a floating-point value from top-left (0, 0) to bottom-right (1, 1) | List<Point2D.Float>

### GpsModel

To view example queries for EXIF data, see EXIF query examples .

One instance of the GpsModel represents one GPS location of a file's content in the P4 Server. The following attributes are stored in Elasticsearch:

Name | Description | Type
--- | --- | ---
location | Elasticsearch compatible location. See Location | Location
altitude | Altitude in meters | Double
bearing | Bearing in degrees from the north | Double

### Location

One instance of the Location represents one Longitude/Latitude location. The following attributes are stored in Elasticsearch:

Name | Description | Type
--- | --- | ---
lat | Latitude in decimal | Double
lon | Longitude in decimal | Double

## (Deprecated) RevisionModel

From the P4 Search 2024.1 release, RevisionModel has been deprecated and will no longer be indexed.

One instance of the RevisionModel represents a single revision of a file in the P4 Server. The following attributes are stored in Elasticsearch:

Name | Description | Type
--- | --- | ---
`type` | Fixed string "revision" | String
`change` | P4 Server change number | Long
`date` | Change date | Long
`depotFile` | Depot file path | String
`action` | P4 Server action, for example: add and edit | String
`fileType` | File type, for example: text, binary, symlink, unicode, utf8, utf16. For more information on file types, see File Types in the P4 CLI Reference | String
`rev` | P4 Server revision number | Integer
fileName | File name | String
`fileSize` | File size in bytes | Long
`digest` | An MD5 digest of the file represented by a 32 hexadecimal digit string | String
`user` | User that submitted the change | String
