ObjectPath

Downloads License Build Status Code Health Coverage Status

We are looking for a maintainer!

Since I'm recently involved in building startup, I'm not able to manage development of ObjectPath in a pace that the community requires. Therefore I'm looking for a person who would help me with maintaining this project especially with tasks of releasing new versions and documenting the language functionality.

If you are interested in taking ObjectPath to the next stage, drop me an e-mail!

The agile NoSQL query language for semi-structured data

#Python #NoSQL #Javascript #JSON #nested-array-object

ObjectPath is a query language similar to XPath or JSONPath, but much more powerful thanks to embedded arithmetic calculations, comparison mechanisms and built-in functions. This makes the language more like SQL in terms of expressiveness, but it works over JSON documents rather than relations. ObjectPath can be considered a full-featured expression language. Besides selector mechanism there is also boolean logic, type system and string concatenation available. On top of that, the language implementations (Python at the moment; Javascript is in beta!) are secure and relatively fast.

ObjectPath makes it easy to find data in big nested JSON documents. It borrows the best parts from E4X, JSONPath, XPath and SQL. ObjectPath is to JSON documents what XPath is to XML. Other examples to ilustrate this kind of relationship are:

Scope Language
text documents regular expression
XML XPath
HTML CSS selectors
JSON documents ObjectPath
