Syntactic Checker

Introduction

These services are a component of the go_bCLEARer toolkit. They provide syntactic analysis of a set of strings in a dataset (e.g. a column). The syntactic analysis is one of the first steps in the bCLEARer evolve stage for string-based columns.

Conceptual Design

Syntactic Check Types

The syntactic checker performs a series of checks based on the configuration file. These checks can be performed across the entire column or within a cell. When performed for the whole column, they provide an overview of the characters used across all columns. When performed within a cell they can cover the entire cell or just a part of it. The full check type classification is as follows (this is a partial taxonomy illustrating the broad structure):

String Check Patterns

These can be defined as fixed strings, regexs or ANTLR grammar rules.

Fixes

The syntactic checker can also implement fixes to the checked data.

For doing this, it uses the string editor services.
