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.
This package is a maintained fork of the original project<htttps://github.com/adriank/ObjectPath>
and still compatible with the specification at the
ObjectPath site<http://objectpath.org/>
.

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

What's in this repo?
ObjectPathPY - Python implementation of ObjectPath, used in production
for over two years without problems. Use objectpath.py file as a example
of usage.
ObjectPathJS - beta version of Javascript implementation. Many tests
passed, {} and functions are not implemented yet. Javascript
implementation has the very same API as the Python version.
