    <p><em>I admit that this is basically a duplicate question of <a href="https://stackoverflow.com/questions/4837936/use-freebase-data-on-local-server">Use freebase data on local server?</a> but I need more detailed answers than have already been given there</em></p> <p>I've fallen absolutely in love with Freebase. What I want now is to essentially create a very simple Freebase clone for storing content that may not belong on Freebase itself but can be described using the Freebase schema. Essentially what I want is a simple and elegant way to store data like Freebase itself does and be able to easily use that data in a Python (CherryPy) web application. </p> <p>Chapter 2 of the MQL reference guide states:</p> <blockquote> <p>The database that underlies Metaweb is fundamentally different than the relational databases that you may be familiar with. Relational databases store data in the form of tables, but the <strong>Metaweb database stores data as a graph of nodes and relationships between those nodes</strong>.</p> </blockquote> <p>Which I guess means that I should be using either a triplestore or a graph database such as Neo4j? Does anybody here have any experience with using one of those from a Python environment?</p> <p>(What I've actually tried so far is to create a relational database schema which would be able to easily store Freebase topics, but I'm having issues with configuring the mappings in SQLAlchemy).</p> <p><strong>Things I'm looking into</strong></p> <ul> <li><a href="http://gen5.info/q/2009/02/25/putting-freebase-in-a-star-schema/" rel="nofollow noreferrer">http://gen5.info/q/2009/02/25/putting-freebase-in-a-star-schema/</a></li> <li><a href="http://librdf.org/" rel="nofollow noreferrer">http://librdf.org/</a></li> </ul> <p><strong>UPDATE [28/12/2011]:</strong></p> <p>I found an article on the Freebase blog that describes the proprietary tuple store / database Freebase themselves use (graphd): <a href="http://blog.freebase.com/2008/04/09/a-brief-tour-of-graphd/" rel="nofollow noreferrer">http://blog.freebase.com/2008/04/09/a-brief-tour-of-graphd/</a></p>

    1. COGiven the first sentence, the right thing to do is open a bounty on the original question.

    3. COWell AFAIK as a third person you can't create a bounty and add an elaboration as to what information is lacking so far in the existing answers. So just putting the bounty on there wouldn't be very useful methinks.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
