that groups together related versions of other entities. Version Sets are primarily used to manage versioned entities like ML models, datasets, and other assets that evolve over time with distinct versions. They provide a structured way to organize, track, and navigate between different versions of the same logical asset.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="identity">Identity<a href="#identity" class="hash-link" aria-label="Direct link to Identity" title="Direct link to Identity"></a></h2><p>Version Sets are identified by two pieces of information:</p><ul><li><strong>ID</strong>: A unique identifier for the version set, typically generated from the platform and asset name using a GUID. This ensures uniqueness across all version sets in DataHub.</li><li><strong>Entity Type</strong>: The type of entities that are grouped in this version set (e.g., <code>mlModel</code>, <code>dataset</code>). All entities within a single version set must be of the same type, ensuring type safety and consistency.</li></ul><p>An example of a version set identifier is <code>urn:li:versionSet:(abc123def456,mlModel)</code>.</p><p>The URN structure follows the pattern: <code>urn:li:versionSet:(<id>,<entityType>)</code> where:</p><ul><li><code><id></code> is a unique identifier string, often a GUID generated from the platform and asset name</li><li><code><entityType></code> is the entity type being versioned (e.g., <code>mlModel</code>, <code>dataset</code>)</li></ul><h2 class="anchor anchorWithStickyNavbar_LWe7" id="important-capabilities">Important Capabilities<a href="#important-capabilities" class="hash-link" aria-label="Direct link to Important Capabilities" title="Direct link to Important Capabilities"></a></h2><h3 class="anchor anchorWithStickyNavbar_LWe7" id="version-set-properties">Version Set Properties<a href="#version-set-properties" class="hash-link" aria-label="Direct link to Version Set Properties" title="Direct link to Version Set Properties"></a></h3><p>Version Sets maintain metadata about the collection of versioned entities through the <code>versionSetProperties</code> aspect. This aspect contains:</p><h4 class="anchor anchorWithStickyNavbar_LWe7" id="latest-version-tracking">Latest Version Tracking<a href="#latest-version-tracking" class="hash-link" aria-label="Direct link to Latest Version Tracking" title="Direct link to Latest Version Tracking"></a></h4><p>The version set automatically tracks which entity is currently the latest version. This is stored in the <code>latest</code> field and provides a quick reference to the most recent version without needing to query all versions.</p><h4 class="anchor anchorWithStickyNavbar_LWe7" id="versioning-scheme">Versioning Scheme<a href="#versioning-scheme" class="hash-link" aria-label="Direct link to Versioning Scheme" title="Direct link to Versioning Scheme"></a></h4><p>Version Sets support different versioning schemes to accommodate various versioning strategies:</p><ul><li><strong>LEXICOGRAPHIC_STRING</strong>: Versions are sorted lexicographically as strings. This is suitable for semantic versioning (e.g., "1.0.0", "1.1.0", "2.0.0") or date-based versions.</li><li><strong>ALPHANUMERIC_GENERATED_BY_DATAHUB</strong>: DataHub generates version identifiers automatically using an 8-character alphabetical string. This is useful when the source system doesn't provide its own versioning.</li></ul><p>The versioning scheme is static once set and determines how versions are ordered within the set.</p><h4 class="anchor anchorWithStickyNavbar_LWe7" id="custom-properties">Custom Properties<a href="#custom-properties" class="hash-link" aria-label="Direct link to Custom Properties" title="Direct link to Custom Properties"></a></h4><p>Like other DataHub entities, Version Sets support custom properties for storing additional metadata specific to your use case.</p><details class="details_lb9f alert
