### 6.4.1 SIF_Metadata

Metadata is commonly referred to as data about data and includes information such as author, grade level, or keywords relating to a learning object, as examples. Metadata can be used to structure and contain any of this kind of information in a consistent manner. In the context of SIF, `SIF_Metadata` provides a consistent structure to appropriate SIF objects for the purpose of cataloging and object discovery, as well as other metadata functions and purposes. One recurring use case within the SIF data model is the requirement for some form of temporal constraints and tagging on objects (see `TimeElement`). Other metadata elements are based on needs brought to the Data Model Task Force.

IMPORTANT NOTE ON PERSISTENCE

This data is not designed to be permanent. It is designed to frame an object instance and could dissolve as soon as it leaves the SIF framework for the application space. A data warehouse could be used to store metadata for later tracking.

IMPORTANT NOTE ON USAGE

Any usage of metadata is optional unless made a requirement within individual SIF objects, or if a SIF or local profile or zone installation mandates it. SIF_Metadata allows for the usage of metadata in agents and applications that choose to support it.

This element is designed to operate much like SIF_ExtendedElements. It is an approved common element that is part of any data object.

### 6.4.2 TimeElement

A common metadata element designed to contain time data, both self-defined and by type.

Figure 6.4.2-1: TimeElement

| Element/@Attribute | Char | Description | Type
--- | --- | --- | --- | ---
| TimeElement |  | A common metadata element designed to contain time data, both self-defined and by type. |
| Type | M | This element is designed to contain the time period attached to an object. Very long periods (school year, quarter, etc.) and very small periods (second, millisecond, etc.) can be defined. This element provides a scoping description of the time metadata enclosed. Because the educational environment varies so greatly we are including here a suggested but not prescriptive list of values. Although there may be unique needs for values not covered here—and we may have missed a major one—a best practice would be to utilize the examples here to enhance interoperability. Examples Full school year Mini-term Long session Other Semester Trimester Quarter Spring Vacation Summer Term Intercession Holiday | xs:normalizedString
| Code | M | This element provides a place for the application to send structured data (code values, unique identifier, timestamps). This code value can, depending upon the use case agreement between agents, be used to qualify the data in the `Value` element. Examples 2007SY 2006.FallConferences | xs:token
| Name | M | Contains a human-readable description of the value in `Value`. Examples Class of '07 Fall 2007 Parent-Teacher Conferences | xs:normalizedString
| Value | M | Contains the human-readable value. Examples 2007 Evening of 10/12/06 | xs:normalizedString
| StartDateTime | O |  | xs:dateTime
| EndDateTime | O |  | xs:dateTime
| SpanGaps | O | A container element for holding multiple possible span gaps. | List
| SpanGaps/SpanGap | OR | This structure duplicates much of the structure of `TimeElement` and is designed to represent a gap in the parent time period defined by `StartDateTime` and `EndDateTime` above. |
| SpanGaps/SpanGap/Type | M |  | xs:normalizedString
| SpanGaps/SpanGap/Code | M |  | xs:token
| SpanGaps/SpanGap/Name | M |  | xs:normalizedString
| SpanGaps/SpanGap/Value | M |  | xs:normalizedString
| SpanGaps/SpanGap/StartDateTime | O |  | xs:dateTime
| SpanGaps/SpanGap/EndDateTime | O |  | xs:dateTime
| IsCurrent | M | This element allows for the system to tag an object as being explicitly current. Although the baseline assumption in SIF is that objects are always current (default value is typically `true`), there are use cases when that is not the case. | xs:boolean

<TimeElement> <Type>Full school year</Type> <Code>01</Code> <Name>2004/2005 School Year</Name> <Value>2004-2005</Value> <StartDateTime>2004-09-01T08:00:00-05:00</StartDateTime> <EndDateTime>2005-06-30T15:00:00-05:00</EndDateTime> <SpanGaps> <SpanGap> <Type>Holiday</Type> <Code>02</Code> <Name>2005 Winter Break</Name> <Value>2005 Winter Break</Value> <StartDateTime>2005-02-21T15:00:00-05:00</StartDateTime> <EndDateTime>2005-02-25T08:00:00-05:00</EndDateTime> </SpanGap> </SpanGaps> <IsCurrent>true</IsCurrent> </TimeElement>

### 6.4.5 EducationFilter

Based on feedback from publishers, instructional management and system integrator vendors, `EducationFilter` was developed to provide the ability to tag objects with metadata that allows for categorization, sorting, and filtering, to empower teaching and learning SIF usage. There exist two main business cases:

- Content providers receiving a request for learning resources can tag content with applicable filters. Upon receipt of SIF objects, receiving application can then read the metadata to categorize the content most appropriately.
- When supported by providers, this metadata can then be utilized in queries to more precisely limit the type of content returned to requesting applications.

The use cases for `EducationFilter` require a contract and choreography to be understood between both sides of the transaction as is the case with all `SIF_Metadata`.

| Element/@Attribute | Char | Description | Type
--- | --- | --- | --- | ---

Although there could be overlap with `LearningStandardItems`, it is anticipated there will be use cases where `LearningStandardItem` objects may not exist or may not be available, and data may need to be tagged with high-level subject areas. | List
| SubjectAreas/SubjectArea | MR |  | SubjectArea
| InterestLevels | O | `InterestLevels` is designed to represent the grade level for which the content is created. For example a tenth grader is at a third grade level in Algebra. You would want to present the content at a third grade level, but in a tenth grade context or interest level. | List

### 6.4.7 StudentLEARelationship

The purpose of the `StudentLEARelationship` object is to represent the current information available regarding a single student's relationship/affiliation to a single LEA for a specific school year as of the time a `SIF_Event` or `SIF_Response` is generated by the system of record. This object is not designed to operate on a historical/longitudinal basis in the default context.

`StudentLEARelationship` instances must not span multiple school years.

Only one instance of the `StudentLEARelationship` object with `MembershipType=Home` may exist for a specific time interval between `EntryDate` and `ExitDate` (inclusive) for a given student, LEA, and school year.

Multiple instances of the `StudentLEARelationship` object with `MembershipType=Concurrent` may exist for a specific time interval between `EntryDate` and `ExitDate` (inclusive) for a given student, LEA, and school year.

Multiple instances of `StudentLEARelationship` will occur for specific or overlapping time intervals if a student has affiliations with multiple LEA's. This will most likely be detected during aggregate data collection from multiple LEA's. Since `StudentLEARelationship/@RefId` and `StudentLEARelationship/@StudentPersonalRefId` are zone-specific, external mechanisms (e.g. student locator) would be required to correlate multiple instances of a single student affiliating with multiple LEA's.

SIF_Events are reported for this object.
