The server acts as <span class="caps">TMQL</span> endpoint for Topic Maps based applications. You can play around with an instance of the server <a href="http://majortom.topicmapslab.de/">here</a>.</p> <p>The sources of the MaJorToM server are available at <a href="http://code.google.com/p/majortom-server/">Google code</a>. In the <a href="http://code.google.com/p/majortom-server/wiki/Deploy">installation instructions</a> you will learn how you can build and deploy your own instances of the MaJorToM server. Once you have deployed the server for your own, you will have an <a href="http://code.google.com/p/majortom-server/wiki/Admin">administration interface</a> and a <a href="http://code.google.com/p/majortom-server/wiki/HTTP"><span class="caps">TMQL</span> interface</a>. But the server is not only a <span class="caps">TMQL</span> endpoint for the data. It also provides full text search (based on <a href="/projects/Beru">Beru</a>) and a <a href="http://code.google.com/p/majortom-server/wiki/HTTP"><span class="caps">SPARQL</span> enpoint</a> to the hosted topic maps.</p> <p>With the next release Maiana will act as a frontend for topic maps delivered by remote MaJorToM server. Besides the Maiana integration the MaJorToM server is very well integrated with <a href="http://code.google.com/p/tm2o/">TM2O - the OData provider</a> for Topic Maps.</p> news@topicmapslab.de (Lutz Maicher) Wed, 27 Apr 2011 08:13:12 +0000 /news/majortom-server-1-0-0-released?locale=de /news/majortom-server-1-0-0-released CouchTM Released <img alt="Seestern_128" src="/document/thumbnail/152/card/seestern_128.png?1303381500" /><p>Apache CouchDB is a document-oriented database that can be queried and indexed in a MapReduce fashion. <a href="http://couchdb.apache.org/docs/intro.html">According to the website CouchDB</a> is:</p> <ul> <li>A document database server, accessible via a RESTful <span class="caps">JSON</span> <span class="caps">API</span>.</li> <li>Ad-hoc and schema-free with a flat address space.</li> <li>Distributed, featuring robust, incremental replication with bi-directional conflict detection and management.</li> <li>Query-able and index-able, featuring a table oriented reporting engine that uses JavaScript as a query language.</li> </ul> <p>Inspired by the increasing impact of NoSQL approaches like CoucDB we developed CouchTM.

The mapping between the Java model and the topic map is defined directly in the related model classes via Java-Annotations. The Annotations hold all information needed by Aranuka which makes it very easy to use Aranuka with an existing model or to change the model or mapping.</p> <p>Besides some bug fixing the new and matured version 1.1.0 has the following new features (<a href="http://code.google.com/p/aranuka/wiki/ChangeLog">see the change log</a>) :</p> <ul> <li>add auto-generate flag to Id annotation → identifiers which are null will be generated if true</li> <li>implemented <span class="caps">TMQL</span> query for session</li> <li>added “addPackage” for class registration</li> <li>using proxies for topic retrieval which enables lazy loading of attributes</li> <li>implements count method of session /admin/documents</li> </ul> <p>If you want to use Aranuka you can build it your own or you can <a href="http://code.google.com/p/aranuka/">download the the latest release at Google code</a>.

The code is published at the <a href="http://code.google.com/p/majortom/source/browse.html#hg%2Fmajortom-redis">MaJorTom Google Code project</a>.</p> <p>The new topic map store is the perfect combination of a light-weight and persistent data store. It enables a parallel access without the need to implement own thread locking mechanism. Redis is easy to administrate and enables very fast read and write access. Additionally it allows replication to multiple servers using its built-in sharding functionality.</p> <p>To make a topic map storage within a Redis database, we recreated the schema of the <a href="http://www.isotopicmaps.org/tmdm/">Topic Maps Data Model</a> based on the Redis possibilities.

In this version tmql4j is more flexible and powerful to satisfy every business use case.</p> <p>As a major modification, the engine architecture and processing model was changed. The new suite contains two different <span class="caps">TMQL</span> runtimes, one for each <span class="caps">TMQL</span> draft. The drafts are split to avoid ambiguity and conflicts during the querying process. The stack-based processing model is replaced by a more flexible one to enable multi-threaded optimizations.</p> <p>Each style of the 2008 draft and each part of the topic map modification language ( <span class="caps">TMQL</span>-ML ) has been realized in different modules. Because of that, the user can decide which styles and parts of the query language should be supported.</p> <p>In addition, a new language module was added to enable flexible template definitions, which enables control of the result format of the querying process in the most powerful way. Templates can be used to return results in <span class="caps">HTML</span>, <span class="caps">XML</span>, <span class="caps">JSON</span> or any other format. The results will be embedded automatically by the query processor.</p> <p>The new version also comes with a couple of other useful features .</p> <ul> <li>In contrast to the draft, the engine supports filter after each navigation step.</li> <li>New axes, like the typed and variants axis, are added to the navigation handler.</li> <li>Result processing has been fully re-implemented, which enables the possibility of empty cells and really atomic cell values.</li> <li>The engine supports result column aliases, similar to <span class="caps">SQL</span>, which can be used to navigate through the result set.</li> <li>The engine supports prepared statements to speed up your application.</li> <li>A couple of new functions are added to fetch the ontology of the topic map or topics by their characteristic values.</li> <li>The new language version comes with a new group-by-clause, that enables an index-based arrangement of the result set.</li> <li>Similar to the select-style, the flwr-style supports the limit-, offset- and unique-clauses.</li> </ul> news@topicmapslab.de (Sven Krosse) Mon, 14 Feb 2011 11:41:46 +0000 /news/tmql4j-300-release?locale=de /news/tmql4j-300-release Onotoa covered by Eclipse magazine <img alt="Original4d3d49968cc3e_1_" src="/document/thumbnail/135/card/original4d3d49968cc3e_1_.png?1297249499" /><p>The latest issue of the Eclipse magazine covers our <span class="caps">TMCL</span> editor Onotoa with an article written by the lead developer Hannes Niederhausen (in German).

But from now on, you may actually watch these updates in a topic map. Each map offers a Map and several Subject Feeds: the Map Feed informs you about all changes in the topic map - the creation of topics, the update of name and occurrence values, the participation in associations and so on. Additionally, using the Subject Feed one may watch a particular topic of interest.</li> <li><strong>Faceted Search</strong>: When searching the full text index of a large topic map with a more general search term, e.g. <a href="https://maiana.topicmapslab.de/u/lmaicher/tm/opera/fulltext_search?endpoint_search=opera">searching the Opera Topic Map for <em>opera</em></a>, the user can easily get lost in the overwhelming number of results. To address this problem, we included the topic types of the search results in a faceted manner. The user is now able to reduce the number of displayed results by selecting and deselecting any topic type she is not interested in.</li> <li><strong><span class="caps">OSM</span>/Google Maps support for geo-typed occurrences</strong>: This is a gadget appearing in maps that include topics representing places. A topic that owns any occurrence of data type <code>http://en.wikipedia.org/wiki/World_Geodetic_System_1984</code> - usually known as the triple of latitude, longitude and an optional value for the height - has a little map icon that reveals an Open Street Map visualization of the given coordinate.</li> </ul> <p><em>October Release</em></p> <ul> <li><strong>New design</strong>: While adding more and more features to Maiana we felt the need to improve the user interface, too. This is a work in progress so stay tuned for more eye candy in the future.</li> <li><strong>Renew <span class="caps">API</span> key</strong>: The Maiana <span class="caps">API</span> key is as <a href="http://projects.topicmapslab.de/projects/maiana/wiki/API_Controller">important</a> as the pair of your user name and password. In any case of security emergency, e.g. if you lost or accidentally published your <span class="caps">API</span> key, you can click on “renew <span class="caps">API</span> key” on your Maiana profile page and the compromised key will be disabled.</li> <li><strong>Maiana <span class="caps">API</span>: Query with <span class="caps">TMQL</span></strong>: The Topic Maps Query Language (<span class="caps">TMQL</span>) is a powerful query language in the field of Topic Maps. With the opening of the Maiana <span class="caps">API</span> for <span class="caps">TMQL</span> queries of all kinds, every Maiana user can now benefit of this power. You can discover how easy it is to use the Maiana <span class="caps">API</span> by having a quick look at the <a href="http://projects.topicmapslab.de/projects/maiana/wiki/API_Controller">Maiana <span class="caps">API</span> documentation</a>.</li> <li><strong>Feature overview for map types</strong>: Have you ever wondered which features of Maiana are available for the different types of maps, e.g. the “Upload” map? You may inform yourself by clicking on the help button at the “Create Topic Map” part on your dashboard or by opening the “Features” tab of a map (e.g. the <a href="https://maiana.topicmapslab.de/u/uta/tm/toytm#features">ToyTM</a>).</li> </ul> <p><em>November Release</em></p> <ul> <li><strong>Container: References Tab</strong>: Maiana Containers are for virtual merging different maps we are calling “references”. In the past, the information about active references was hidden for every user except the owner of the container. Now, the new “Reference” tab reveals this useful information: for example, it <a href="https://maiana.topicmapslab.de/u/maiana/tm/operas#references">shows</a> which maps have been merged to create the “Operas” Container.</li> <li><strong>Social Tab and Editors</strong>: Maiana wants to be a <em>social</em> topic maps platform. With the introduction of the new “Editor” role this is now taken to a new level. Any user who has been invited as editor to a map in the “Social” tab may now view this map (similar to users that own the “Viewer” role) <span class="caps">AND</span> may edit it in the web-interface or by executing <span class="caps">TMQL</span> update queries.</li> <li><strong>Maiana <span class="caps">API</span>: Search in maps</strong>: While having remote access to the data structure of a topic map with the <span class="caps">TMQL</span> querying facility of the Maiana <span class="caps">API</span> is great, the flexibility of <span class="caps">TMQL</span> may sometimes be unnecessary. For this reason, we opened up the full text search functionality of Maiana with the new <span class="caps">API</span> method called <code>search_endpoint</code>. You can perform any search and receive the results as <span class="caps">JSON</span> objects as described in the <a href="http://projects.topicmapslab.de/projects/maiana/wiki/API_Controller">Maiana <span class="caps">API</span> documentation</a>.</li> <li><strong><span class="caps">RDF</span>/N3 export of a topic map</strong>: When speaking about the Semantic Web, one usually thinks of <span class="caps">RDF</span> in one of its various formats. We strongly support the Semantic Web ideas of opening up data silos and connecting all available public data. And we want Maiana to play its part in this game. So we made the export of whole Maiana maps as <span class="caps">RDF</span>/<span class="caps">XML</span> and <span class="caps">RDF</span>/N3 easily available in the “Download map data” menu of each downloadable map.</li> <li><strong>New map type: <span class="caps">XLS</span></strong>: We love Topic Maps and structured data in general. But the vast majority of data out there is semi- to unstructured. In the continuing effort to provide tools for better handling of data, we introduced the new “<span class="caps">XLS</span>” map type that allows the upload of a mapping definition file for Excel files. This way, the tabular-structured components of an Excel file may be viewed and used like any other topic map.</li> <li><strong>Renaming of <span class="caps">JLI</span> to DB</strong>: To distinguish between <span class="caps">JLI</span> access to Excel files and relational databases we renamed the former “<span class="caps">JLI</span>” part of the “Create topic map” form to “DB”.</li> </ul> <p><em>December Release</em></p> <ul> <li><strong>Notifications</strong>: We introduced notification e-mails that inform about users following you and watching or commenting on your maps. Of course, the notifications may be deactivated on the profile page.</li> </ul> <p>Excel is either a registered trademark or a trademark of Microsoft Corporation in the United States and/or other countries.</p> news@topicmapslab.de (Uta Schulze) Wed, 22 Dec 2010 16:26:53 +0000 /news/maiana_2010_release?locale=de /news/maiana_2010_release
