This property contains the ID that was originally assigned by Illustrative Mathematics. The field is available in both flat file downloads and REST API responses. ### API updates #### API Keys for REST API and MCP server You can now create API keys to access our REST API and MCP server on the [Learning Commons Platform](https://platform.learningcommons.org/) ↗. #### Academic standards search API endpoints The existing standards search endpoint now supports semantic search. Find standards by concept in addition to exact statement code lookup. Supports filtering by grade, subject, and statement type. #### Learning component search API endpoints **Search learning components** — New endpoint to find learning components by description using semantic search. Results are ranked by relevance score. ### Data v1.6.0 #### Learning component aligned states We've added alignments to learning components and crosswalks to Common Core for standards from: * Kansas #### Data quality improvements * We've updated some of the alignments between learning components and the Massachusetts state standards to address inconsistencies. * We've fixed the direction of the `hasDependency` relationship between curriculum components in Illustrative Mathematics content. ### API updates #### Curriculum scope and sequence REST API endpoints We've introduced a new set of curriculum endpoints and expanded our academic standards lookup capabilities. **Curriculum** * New endpoints provide structured access to curriculum metadata for IM® 360 scope and sequence * Access courses, scope and sequence, lesson groupings (units/modules), lessons, activities, and assessments * View academic standards aligned to lessons, activities, and assessments. Note: instructional materials (lesson/activity/assessment content) are not included **Academic Standards** * Added three new endpoints to retrieve lessons, activities, and assessments aligned to a specific academic standard by CASE UUID ### Data v1.6.0 #### Learning component aligned states We've added alignments to learning components and crosswalks to Common Core for standards from: * North Carolina ### Data v1.5.0 #### Learning component aligned states We've added alignments to learning components and crosswalks to Common Core for standards from: * Florida * Idaho * Mississippi * Ohio * South Dakota * Utah ### Data v1.4.0 #### Learning component aligned states We've added alignments to learning components and crosswalks to Common Core for standards from: * Massachusetts #### IM® 360 scope and sequence (CC BY-4.0) The scope and sequence for the IM® 360 curriculum by Illustrative Mathematics® is now available under a CC BY-4.0 license. #### Learner variability navigator We've added the relevantToStandard relationship that links a Factor to a StandardFrameworkItem for Common Core ELA standards. #### WIDA English Language Development Standards A reference to WIDA English Language Development Standards for English language learners has been added to the documentation. These standards were in the graph but not documented before this release. ### Data v 1.3.0 #### Graph-native JSON The Knowledge Graph data is available for download in newline-delimited JSONL format with UTF-8 encoding. #### CSV deprecation The Knowledge Graph can no longer be downloaded as CSV flat files from v1.3.0 onwards. Any previously downloaded CSV flat files will remain unaffected. ### Data v1.2.0 #### Learning component aligned states We've added alignment between learning components and standards for the following states: * Wisconsin #### Crosswalks You can now compare the individual state standards to their alignment to Common Core state standards using four new fields. [Learn more](/knowledge-graph/entity-and-relationship-reference/crosswalks). #### Learner Variability Navigator The Learner Variability Navigator dataset from Digital Promise is now available. Contact [support@learningcommons.org](mailto:support@learningcommons.org) ↗ for information about getting access. ### Attribution statement We've updated our attribution statement to reflect the name Learning Commons. ### Data v1.1.0 #### Learning component aligned states We've added alignment between learning components and standards for the following states: * Louisiana * Montana * Pennsylvania * Washington, D.C. #### Academic standards We've added academic standards for Washington, D.C.
