+description: How to customize data models for ENSNode, using the ENSNode Plugin specification.

+
+## What is an ENSNode Plugin?
+
+An **ENSNode Plugin** is an abstract specification that defines how a specific aspect of the ENS namespace is indexed into [ENSDb](/docs/services/ensdb). It is **not** an implementation — it is a standard that any [ENSDb Writer](/docs/services/ensdb/concepts/glossary#ensdb-writer) can implement.
+
+Each ENSNode Plugin defines:
+
+- **Name** — e.g. `unigraph`, `protocol-acceleration`, `subgraph`.
+- **Datasources** — which onchain contracts should be indexed, as a function of the ENS namespace.
+- **Dependency relationships** — other plugins that must (or must not) be activated concurrently.
+- **Indexed data model** — the tables, columns, and indexes that the plugin produces in ENSDb.
+- **Standards and invariants** — rules for how onchain events are translated into the indexed data model during indexing.
+- **Versioning** — a version number that can be stored in ENSNode Metadata, to track which version of the plugin implementation is being used by ENSDb Writers and ENSDb Readers.
+
+## Why ENSNode Plugins Matter
+
+ENSNode Plugins are the key architectural piece that enables a decoupling between [ENSDb Writers](/docs/services/ensdb/concepts/glossary#ensdb-writer) and [ENSDb Readers](/docs/services/ensdb/concepts/glossary#ensdb-reader), so that anyone can create their own implementations of these. For example, any team working on indexing infrastructure can implement an ENSDb Writer and have it produce a standards-compliant ENSDb. On the other hand, any team working on products for ENS ecosystem can build their own standards-compliant ENSDb Reader and have it query ENSDb.
+
+:::note[Interoperability between ENSDb Writers and Readers]
+When new ENSNode plugins are created, it becomes possible for the [ENS Omnigraph API](/docs/integrate/omnigraph) (or other APIs built by any ENSDb Reader) to unify the ability to query across ENSNode plugins in a single query. For example, you could query both ENS state from the `unigraph` and EFP state about followers from the `efp` plugin in a single GraphQL query.
+:::
+
+## Core Plugins
+
+[ENSIndexer](/docs/services/ensindexer) is a reference implementation of an [ENSDb Writer](/docs/services/ensdb/concepts/glossary#ensdb-writer) that implements multiple core plugins following the ENSNode Plugins specification. The code for each plugin inside ENSIndexer is a reference implementation of that plugin's abstract specification.
