Description : Yet Another Query Language
At the beginning of millennium the growing trend towards data formats
standardization and application integrability made XML extremely popular. XML
became lingua franca of the data. Applications tended to process lots of XML
files ranging from small config files to very large datasets. As these data
often had a complex structure with many levels of nestedness it is quickly
became obvious that there is a need for specially crafted domain specific
languages to query these data sets. This is how XPath and later XQL were born.
.
With later popularization of REST services and Web 2.0 JSON started to take
XML’s place. JSON’s main advantage (besides being simpler than XML) is that is
closely reassembles data structures found in most programming languages
(arrays, dictionaries, scalars) making it very convenient for data
serialization. As JSON lacked all the brilliant XML-related technologies like
XSLT, XML Schema, XPath etc. various attempts to develop similar languages for
JSON were made. One of those efforts was JSONPath library developed in 2007 by
Stefan Gössner. Initial implementation was for PHP and JavaScript languages,
but later on ports to other languages including Python were written. YAQL is
one of the implementations in Python.
