redis_triplestore 0.1

redis_triplestore

使用Python实现了一个基于Redis存储关系的三库。

需要Redis 2.0+，redis-py和redis_wrap的最新版本。

redis-py可以从这里下载： * http://github.com/andymccurdy/redis-py

请注意，您可以使用requirements.txt文件使用pip安装依赖项。

示例

归属

FOAF = Namespace('http://xmlns.com/foaf/0.1/')

frodo = Resource('http://example.com/comte/frodo', **{
    FOAF.name: 'Frodo',
    FOAF.familyName: 'Baggins',
})
assert frodo[FOAF.name] == 'Frodo'

持久性

frodo = Resource('http://example.com/comte/frodo')
assert frodo[FOAF.name] == 'Frodo'

gandalf = Resource('http://example.com/wizards/gandalf', **{
    FOAF.name: 'Gandalf',
    FOAF.familyName: 'the White',
})
saruman = Resource('http://example.com/wizards/saruman', **{
    FOAF.name: 'Saruman',
    FOAF.familyName: 'of Many Colors',
})

关系

frodo.add_relation(FOAF.knows, gandalf)
assert frodo.relations(FOAF.knows) == [gandalf]
gandalf.add_relation(FOAF.knows, saruman)
assert gandalf.relations(FOAF.knows) == [saruman]
assert gandalf.reversed_relations(FOAF.knows) == [frodo]
frodo.add_relation(FOAF.knows, saruman)
assert frodo.relations(FOAF.knows) == [gandalf, saruman]

清理

frodo.delete_relation(FOAF.knows, saruman)
assert frodo.relations(FOAF.knows) == [gandalf]
frodo.delete_relation(FOAF.knows, gandalf)
gandalf.delete_relation(FOAF.knows, saruman)
assert gandalf.relations(FOAF.knows) == []
assert gandalf.reversed_relations(FOAF.knows) == []
frodo.remove()
gandalf.remove()
saruman.remove()
assert frodo[FOAF.name] == None
