It should be noted that the dumps for research communities, infrastructures, and products related to projects do not strictly follow the main data model of the OpenAIRE Graph. In particular, they differ in the following: It should be noted that the datasets for research communities, infrastructures, and products related to projects do not strictly follow the main data model of the OpenAIRE Graph. In particular, they differ in the following:
* only research products are dumped (no relations, and entities different from results) * only research products are included (no relations, and entities different from results)
* the dumped results are extended with information that can be inferred in the whole dump namely: * the results are extended with information that can be inferred in the whole dataset namely:
* funding information if present * funding information if present
* associated research community/infrastructure * associated research community/infrastructure
* associated data sources * associated data sources

## Alternative sub-graph data model ## Alternative sub-graph data model
It should be noted that the dumps for research communities, infrastructures, and products related to projects do not strictly follow the main data model of the OpenAIRE Graph. In particular, they differ in the following: It should be noted that the datasets for research communities, infrastructures, and products related to projects do not strictly follow the main data model of the OpenAIRE Graph. In particular, they differ in the following:
* only research products are dumped (no relations, and entities different from results) * only research products are included (no relations, and entities different from results)
* the dumped results are extended with information that can be inferred in the whole dump namely: * the results are extended with information that can be inferred in the whole dataset namely:
* funding information if present * funding information if present
* associated research community/infrastructure * associated research community/infrastructure
* associated data sources * associated data sources
So they have just one entity type, that is the [Extended Result](alternative-model/extendedresult.md). So they have just one entity type, that is the [Extended Result](alternative-model/extendedresult.md).
