Standard and idiosyncratic schemata for text, annotation and user data, with a library of validation, (de-)serialization, a database interface and other utilities.
This module defines:
- shared standard schema for communicating and storing data (with a particular focus on sanskrit texts) of various types.
- various idiosyncratic notations used by various modules which deviate from the proposed standards.
- python classes (corresponding to the schema) and shared libraries for validating, (de-)serializing and storing sanskrit data of various types.
- a common database interface for accessing various databases (so that a downstream app can switch to a different database with a single line change).
While this package was originally motivated by Sanskrit text annotation needs, it is more generally useful.
Similar libraries in various other programming languages are being built:
- Scala (likely compatible with Java): db-interface .
- Various sanskrit modules need to communicate data amongst each other
(for example through a REST API or database stores or even function
calls). Examples of the data being communicated could be:
- Gramatical details of a given word
- Sentences in a given book chapter
- Annotations on a given phrase
- When it comes to serialization formats - two distinct approaches
present themselves to us:
- One possible route is to have each project defining and using its
own idiosyncratic notation. But this entails an additional
- Each communicating module having to convert the data from one idiosyncratic notation to another.
- Good schema design or notation is non trivial. Even if no external module is using the data, it is a waste to have to reinvent the wheel.
- A superior route is to have a common, standard format for encoding various data-types for storage/ communication.
- One possible route is to have each project defining and using its own idiosyncratic notation. But this entails an additional burdens:
- To the extant possible, we should take latter approach to data storage and communication.
- Where idiosyncratic notations are adapted for various reasons, it is still desirable to collect such definitions in a single module - to facilitate conversion to the standard format.
- Install this library (Replace pip2 with pip3 as needed)
