Attributes ¶

Context chain¶

Sometimes actions provided by the EP object service can operate upon objects within a particular EP context: that is an EP object can be visible within the context of another EP object, which can be visible within the context of yet another object. You can envision this structure as a tree where each object is a node in the tree, within the context of parentage all the way back to a root object that you as an EP user have ownership or direct permissions upon.

The context chain for an object is the linear (inclusive) list of nodes between an object all the way back to this root object, and is typically expressed as a comma-separated list.

EPASSOC_T¶

Two kinds of EP objects can support association: Reflections, and Learning Objectives. We use the term EPASSOC_T to stand in for an appropriate identifying integer value.

Object association type	Value
Reflection	1
LearningObjective	2

EPOBJ_T¶

EP objects provide a generic data structure base from which a number of specific forms derive. In EpObject blocks, the ObjectTypeId property encodes the specific type of the data structure, as an integer value. In this reference we use the term EPOBJ_T to stand in for an appropriate integer value.

Object type	Value
EpObject	0
Collection	100
StaticCollection	110
DynamicCollection	120
Reflection	200
Artifact	300
FileArtifact	310
FormArtifact	320
LEArtifact	330
LECompetencyArtifact	331
LEGradeArtifact	332
LEQuizArtifact	333
LEDropboxArtifact	334
UrlArtifact	340
Presentation	400
LearningObjective	600

OBJRIGHT_T¶

The rights that EP users can be granted on an EP object when it is shared to them; the rights are organized into a discrete list of rights. We use the term OBJRIGHT_T to stand in for an appropriate integer value.

Object right type	Value
View	1
SeeComments	2
AddComments	3
ViewAssessments	4
AddAssessments	5
Edit	6

PERMPROFILE_T¶

Permission profiles are organized into several general groups. We use the term PERMPROFILE_T to stand in for an appropriate integer value.

Permission profile type	Value
Container	1
OrgUnit	2
Individual	3

THUMBSZ¶

The EP service supports thumbnailing of objects, at several preset sizes. We use the term THUMBSZ to stand in for an appropriate integer value.

Thumbnail size	Value
ReallySmall	24
Small	36
Medium	50
Large	300
ReallyLarge	800

EP.EpObject¶

Create. When you use actions that provide EP object data to the service, you should provide a block that looks like this:

{
    "ObjectId": <number:D2LID>,
    "Name": <string>,
    "Description": <string>,
    "Tags": [ <EP.TagObject>, ... ],
    "GeoTag": { <composite:EP.GeoTag> },
    "AllowComments": <boolean>
}

Warning

You should never seek to modify the ObjectId property of an EP object once the service has established it; rather, if you use an action to update an EP object, you should just reflect back the ObjectId value provided to you by the service for the object in the first place.

However, when you use an action to create a new EP object (and the service hasn’t yet given you an ObjectId you can use), you should be sure to set the ObjectId property to zero ("ObjectId":0) to indicate to the service that you want it to create a new object and allocate a new ID.

Fetch. When you use actions that retrieve EP object data, the service provides a block like this:

{
    "ObjectId": <number:D2LID>,
    "Name": <string>,
    "Description": <string>,
    "UserId": <number:D2LID>,
    "ObjectTypeId": <number:EPOBJ_T>,
    "ViewLink": <string>,
    "CommentsCount": <number>,
    "HasUnreadComments": <boolean>,
    "Tags": [ <EP.TagObject>, ... ],
    "Comments": [ <EP.ObjectComment>, ... ],
    "Created": <string:UTCDateTime>|null,
    "Modified": <string:UTCDateTime>|null,
    "GeoTag": { <composite:EP.GeoTag> },
    "AllowComments": <boolean>,
    "Permissions": [ <number:OBJRIGHT_T>, ... ]
}

Permissions: If this property is present, it contains an array of object right type values to encapsulate the permissions granted to EP users when the object gets shared to them.

EP.ObjectComment¶

{
    "CommentId": <number:D2LID>,
    "UserId": <number:D2LID>|null,
    "FirstName": <string>,
    "LastName": <string>,
    "CommentBody": <string>,
    "CreatedDate": <string:UTCDateTime>,
    "CommentedObjectId": <number:D2LID>,
    "ContextObjectId": <number:D2LID>|null,
    "ContextObjectTypeId": <number>|null
}

ContextObjectTypeId: When it appears, this value is a simplified version of an EPOBJ_T value. It can have a value of 0 (for a generic EP object) or one of the EPOBJ_T values evenly divisible by 100 (that is, the values for Collection, Reflection, Artifact, Presentation, Learning Objective). It can also have a value of 5 indicating an EP Form.

EP.GeoTag¶

The GeoTag object gets used to encode the geo-tagging information to describe the real-world location associated with an EP object.

{
    "Latitude": <number>,
    "Longitude": <number>,
    "Altitude": <number>|null,
    "Bearing": <number>|null,
    "Precision": <number>|null
}

Note

All the properties in a GeoTag structure get interpreted by the service as a C# decimal numeric type, that is, a high-precision, small-range floating point value.

EP.UserObject¶

{
    "UserId": <number:D2LID>,
    "FirstName": <string>,
    "LastName": <string>
}

EP.Share¶

{
    "ProfileId": <number:D2LID>,
    "Id": <number:D2LID>,
    "Type": <number:PERMPROFILE_T>,
    "Name": <string>,
    "Permissions": [ <number:OBJRIGHT_T>, ... ]
}

ProfileId: Profile identifier for the EP sharing group (note that this is not the same thing as a Brightspace user’s ProfileId for the user profile).
Id: System identifier for the share target (i.e. UserId if the target is a user)
Permissions: If present, an array of object right type values to encapsulate the permissions granted to the user being shared to.

EP.ShareTarget¶

{
    "Id": <number:D2LID>,
    "TargetId": <number:D2LID>,
    "Name": <string>,
    "ProfileType": <number:PERMPROFILE_T>
}

Id: Identifier for the EP sharing group.
TargetId: System identifier for the share target (i.e. UserID if the target is a user).

Object query filters ¶

The actions provided by the EP object service allow you to set a complex query filter string to narrow the number of elements in the returned result set. An object query filter consists of one or more simple relational expressions chained together with the .AND. and .OR. conjunctive operators. Each simple relational expression tests a single property against a value with a relational operator.

Property	Operators	Test against…
type	=, !=	Type of the object
id	=	Object ID
user	=, !=	ID for the user owning the object
name	=, ^, ^^	Object name string
desc	=, ^, ^^	Object description string
created	=, >, <, >=, <=	Date object was created (in ISO 8601 forma
modified	=, >, <, >=, <=	Date object was last modified (in ISO 8601 format)

^: Produces true if the L-value property starts with the R-value string.
^^: Produces true if the R-value string occurs somewhere within the L-value property.
type: Filters can only sift on type at a granularity of basic EP object types (that is, collections, reflections, artifacts, and presentations – those with a type value evenly divisible by 100). If you use a type expression to specify any derived type, the filter will select for its associated basic type and any objects derived from it (for example, if you provide ?q="type=110", this will fetch all objects of type 100, 110, or 120).

Example. If you want to select for all results shared to user ID 2046 but created after 20 May, 2004: ?q="user=2046.AND.created>=2004-05-20".
