Methods, systems, and computer-readable media for a query language for selecting and addressing resources are disclosed. Records are stored in a data store. The records comprise attribute data descriptive of resources managed by a provider network. The data store is queried to select one or more records matching one or more values of the attribute data. The query is expressed using a query language. A resource group is determined based (at least in part) on the query. The resource group comprises one or more resources corresponding to the one or more records selected by the query.
