'''This module provides an abstraction of controlled vocabularies. |
|
4
|
|
|
|
|
5
|
|
|
This abstraction allows our application to work with both local and remote |
|
6
|
|
|
vocabs (be they SOAP, REST, XML-RPC or something else). |
|
7
|
|
|
|
|
8
|
|
|
The basic idea is that we have skos providers. Each provider is an instance |
|
9
|
|
|
of a :class:`VocabularyProvider`. The same class can thus be reused with |
|
10
|
|
|
different configurations to handle different vocabs. Generally speaking, every |
|
11
|
|
|
instance of a certain :class:`VocabularyProvider` will deal with concepts and |
|
12
|
|
|
collections from a single conceptscheme. |

A provider that reads a simple csv format into memory. |
|
603
|
|
|
|
|
604
|
|
|
The supported csv format looks like this: |
|
605
|
|
|
<id>,<preflabel>,<note>,<source> |
|
606
|
|
|
|
|
607

This provider essentialy provides a flat list of concepts. This is commonly |
|
608
|
|
|
associated with short lookup-lists. |
