# Enrich

The **Enrich** step uses linked data that is asserted in the [internal store](https://docs.triply.cc/triply-etl/generic/internal-store/) to derive new linked data.

```mermaid
graph LR
  sources -- 1. Extract --> record
  record -- 2. Transform --> record
  record -- 3. Assert --> ld
  ld == 4. Enrich ==> ld
  ld -- 5. Validate --> ld
  ld -- 6. Publish --> destinations

  destinations[("D. Destinations\n(TriplyDB)")]
  ld[C. Internal Store]
  record[B. Record]
  sources[A. Data Sources]
```

TriplyETL supports the following languages for making enrichments:

- [**SHACL Rules**](https://docs.triply.cc/triply-etl/enrich/shacl/) allows the implementation of business rules that can add linked data to the internal store. TriplyETL supports the following forms of SHACL Rules:

    - [**Triple Rules**](https://docs.triply.cc/triply-etl/enrich/shacl/triple-rules/)
    - [**SPARQL Rules**](https://docs.triply.cc/triply-etl/enrich/shacl/sparql-rules/)

- SPARQL is a query language that can also be used to add and remove data. This allows SPARQL to be used as an enrichment language. TriplyETL supports the following forms of SPARQL enrichment:

    - [**SPARQL Construct**](https://docs.triply.cc/triply-etl/enrich/sparql/construct/) allows linked data to be added to the internal store.
    - [**SPARQL Update**](https://docs.triply.cc/triply-etl/enrich/sparql/update/) allows linked data to be added to and deleted from the internal store.

If you have not loaded any linked data in your Internal Store yet, use one of the following approaches to do so:

- [loadRdf()](https://docs.triply.cc/triply-etl/extract/rdf/)
- [JSON-LD Expansion](https://docs.triply.cc/triply-etl/assert/json-ld/)
- The RATT [statement assertion](https://docs.triply.cc/triply-etl/assert/ratt/statements/) functions.
