Punya Framework

Punya is a framework for building mobile applications that use Linked Data, addressing the difficulty of consuming and generating Linked Data on smartphones. It targets the problem of data integration across distributed sources, such as crowdsourced information, relief organizations, and government agencies, where applications typically operate in silos with standalone databases or spreadsheets. By applying Linked Data principles, it supports the reuse, extension, and integration of heterogeneous structured data.

The framework provides components including LinkedData, LinkedDataForm, SemanticListPicker, Ruleset blocks, Reasoner, Survey, GoogleCloudMessaging, and LdpCoapClient. These support tasks such as semantic annotation of form entries, querying external ontologies, defining and executing rules for on-device decision support, push notifications, and publishing or discovering resources as Linked Data Platform resources over LDP-CoAP. Example applications cover disaster resource matching, reporting damage, experience sampling with device sensors, patient diaries, and diabetes management.

Punya is aimed at developers and volunteers working with humanitarian organizations, as well as researchers building mobile apps for data collection, decision support, and sensor data. The pages describe tutorials for specific implementations but do not state a pricing or packaging model.
