OpenCGA Catalog Data Models
In this section all the Catalog data models will be explained.
For more detailed information about the Java data models you can browse the source code at Java beans.
Fields that are common between the data models are:
- id: a numeric positive identifier which is unique in the whole Catalog. This id can be used in the API and REST web services.
- status: Java bean object containing the actual status of the entity (user, project, study...). By default, the accepted ones are READY, TRASHED and DELETED, although some entities extend this java bean and defines more.
- attributes: this field can be used by different applications using OpenCGA to store custom information, any well-formed JSON object is accepted.
- lastActivity: this field reports when was the last time the data was updated, this is useful when updating a web client interface. []: # (For a lastActivity known value, if the value matches with the stored, it is not necessary to)
Register every login and logout made by the user. The sessionId is valid only while the field logout is empty.
🚧 The session array will be taken care of by a low latency daemon that will be running in the background in the future.
This is the root level of the hierarchy. It represents any person registered in the system together with their projects.
Most relevant fields are:
- id: Alphanumerical string identifier. This is the only non-numerical Id.
-
status: Additional status besides the default ones:
-
BANNED:
-
-
account: Accepted account types:
-
GUEST: This account type is for guests only, so they will not be able to create their own projects or studies. -
FULL: This account type is for the most general use that gives complete access to openCGA allowing to define new projects and studies.
-
- configs: 🚧 In the config map, the user will be able to store their own queries and recover them giving them a name.
Example:
{
"id": "jsmith",
"name": "John Smith",

Main Catalog object. A study is a set of, among others, files, jobs and samples. All the files in a study share location, cypher and sharing options (ACLs).
Most relevant fields are:
-
type: (to cohort?)
-
CASE_SET: -
CONTROL_SET: -
CASE_CONTROL: -
PAIRED: -
FAMILY: -
TRIO:
-
- stats: (to cohort?)
-
status:
-
ACTIVE:
-
- diskUsage: Sum of the diskUsage of all files in the study.
-
cipher: Mechanism used to cypher all files in study. Accepted values:
-
NONE: Without encryption. -
AES_256: not implemented yet
-
- uri: Location of the study. An URI is required instead of a Path because the study could be in different hosts and file systems.
Example:
{
"id": 15,
"name": "Study test 1",
"alias": "std1",
