Installation

TopicDB officially supports Python 3.3–3.6. To install TopicDB, simply:

$ pip install topic-db

First-Time Use

import os

from topicdb.core.commands.topic.gettopic import GetTopic
from topicdb.core.commands.topicmap.gettopicmap import GetTopicMap
from topicdb.core.commands.topicmap.settopicmap import SetTopicMap


DATABASE_PATH = os.path.join(os.path.dirname(__file__), 'test-topicmap.db')
MAP_IDENTIFIER = 1
TITLE = 'Topic Map'
DESCRIPTION = 'Default topic map'

print('Creating and initializing topic map')
SetTopicMap(DATABASE_PATH, MAP_IDENTIFIER, TITLE, DESCRIPTION).execute()

# Rest of the code is for testing purposes (e.g., to verify that the topic map has been created
# and that the 'entry' topic can be retrieved.
print("\nGetting topic map")
topic_map = GetTopicMap(DATABASE_PATH, MAP_IDENTIFIER).execute()

print("Map identifier: [{0}]".format(topic_map.identifier))
print("Map title: [{0}]".format(topic_map.title))
print("Map description: [{0}]".format(topic_map.description))
print("Map entry topic: [{0}]".format(topic_map.entry_topic_identifier))

print("\nGetting entry topic")
topic = GetTopic(DATABASE_PATH, MAP_IDENTIFIER, 'genesis').execute()

print("Topic identifier: [{0}]".format(topic.identifier))
print("Topic 'instance of': [{0}]".format(topic.instance_of))
print("Topic (base) name: [{0}]".format(topic.first_base_name.name))
