Use these browsing requests individually or in conjunction with [querying](query-via-the-datasets-api). For instance, entities located through browsing are resources which can be the subject of a query. On this page, learn about requests to return: * [datasets you can access](#section-return-accessible-datasets) * [all the entities within a dataset](#section-return-all-entities-within-a-dataset) * [all instances of a single entity](#section-return-all-instances-of-an-entity) * [a single entity's metadata schema](#section-return-an-entity-s-metadata-schema) <div align="right"><a href="#top">top</a></div> ##Return accessible datasets Make the following `GET` request.

Each entity has its own metadata schema, a list of the metadata fields used to describe the entity and the permissible datatypes (strings, integers, etc) that each field takes. Each metadata field, such as `hasDataType` in the request below, is followed by an object which indicates the type of value for each field, such as `integer`, `string`, or `enum`. If the type is given as `enum`, the object also contains a list of all possible values for the given metadata field. Additionally, note that under `_links`, there is a list of connections to other entities in the dataset. In the example below, these connections include `"hasAliquot"`, `"hasCase"`, `"hasSample"`, `"hasPortion"`, and `"hasAnalyte"`. For example, to see the metadata schema for `files` send the request: [block:code] { "codes": [ { "code": "GET /datasets/tcga/v0/files/schema HTTP/1.1\nHost:
