Schemio is a powerful .NET library designed to aggregate data from heterogeneous data stores using a schema-driven approach. It enables developers to hydrate complex object graphs by fetching data from multiple sources (SQL databases, Web APIs, NoSQL stores) using XPath and JSONPath schema mappings.

Package	Latest	Details
Schemio.Core		Provides core functionality to configure nested queries and transformers. With ability to map schema paths (XPath/JSONPath) to entity's object graph. No QueryEngine provided and requires implementing IQueryEngine to execute IQuery instances.
Schemio.SQL		Provides schemio with query engine using Dapper to execute SQL queries.
Schemio.EntityFramework		Provides schemio with Entity Framework query engine to execute queries using DbContext.
Schemio.API		Provides schemio with Web Api query engine to execute apis using HttpClient.

Schemio is a data aggregation framework using queries that can target different data platforms.

Key benefits:

• allows fetching aggregated data from heterogeneous data storages. You could combine queries targetting different data platforms (example. SQL, API, Cache) to return an aggregated data entity.
• allows conditional fetching of parts of the aggregated data entity. You could retrieve parts of object graph in the aggregated entity by specifying schema paths (using XPath or JSonPath) to identify respective sections.
