Wandora – New Release – 2016-03-08

The homepage reports:

New Wandora version has been released today (2016-03-08). The release adds Wandora support to MariaDB and PostgreSQL database topic maps. Wandora has now more stylish look, especially in Traditional topic map. The release fixes many known bugs.

I’m no style or UI expert but I’m not sure where I should be looking for the “…more stylish look….” 😉

From the main window:


If you select Tools and then Tools Manager (or Cntrl-t [lower case, contrary to the drop down menu]), you will see a list of all tools (300+) with the message:

All known tools are listed here. The list contains also unfinished, buggy and depracated tools. Running such tool may cause exceptions and unpredictable behavior. We suggest you don’t run the tools listed here unless you really know what you are doing.

It is a very impressive set of tools!

There is no lack of place to explore in Wandora and to explore with Wandora.


Wandora – 2015-11-13 Release

Friday, November 13th, 2015

Wandora (download page)

The change log is rather brief:

Wandora 2015-11-13 fixes a lot of OS X related bugs. Release introduces enhanced subject locator previews for WWW resources, including videos, images, audio files and interactive fiction (z-machine). The release has been compiled and tested in Java 8.

Judging from tweets between this release and the prior one, new features include:

  • Subject locator preview for web pages
  • Subject locator preview for a #mp3 #ogg #mod #sidtune #wav

If you are new to Wandora be sure to check out the Wandora YouTube Channel.

I need to do an update on the Wandora YouTube Channel, lots of good stuff there!

IoT Pinger (Wandora)

Tuesday, July 28th, 2015

IoT Pinger (Wandora)

From the webpage:

This is an upcoming feature and is not included yet in the public release.

The IoT (Internet of Things) pinger is a general purpose API consumer intended to aggregate data from several different sources providing data via HTTP. The IoT Panel is found in the Wandora menu bar and presents most of the pinger’s configuration options. The Pinger searches the current Topic Map for topics with an occurrence with Source Occurrence Type. Those topics are expected to correspond to an API endpoint defined by corresponding occurrence data. The pinger queries each endpoint every specified time interval and saves the response as an occurrence with Target Occurrence Type. The pinger process can be configured to stop at a set time using the Expires toggle. Save on tick saves the current Topic Map in the specified folder after each tick of the pinger in the form iot_yyyy_mm_dd_hh_mm_ss.jtm.

Now there’s an interesting idea!

Looking forward to the next release!

Wandora – Heads Up! New release 2015-04-20

Thursday, April 16th, 2015

No details, just saw a tweet about the upcoming release set for next next Monday.

The latest date that the new web search application from DARPA will drop as well.

Could be the start of a busy week!

Wandora tutorial – OCR extractor and Alchemy API Entity extractor

Wednesday, March 18th, 2015

From the description:

Video reviews the OCR (Optical Character Recognition) extractor and the Alchemy API Entity extractor of Wandora application. First, the OCR extractor is used to recognize text out of PNG images. Next the Alchemy API Entity extractor is used to recognize entities out of the text. Wandora is an open source tool for people who collect and process information, especially networked knowledge and knowledge about WWW resources. For more information see

A great demo of some of the many options of Wandora! (Wandora has more options than a Swiss army knife.)

It is an impressive demonstration.

If you aren’t familiar with Wandora, take a close look at it:

From the change log:

This release enhances Wandora’s UI.

  • View menu has been restructured. Now the View menu contains a submenu for each open topic panel.
  • Search (topic) panel. Open any number of distinct searches and queries. Use menu option View > New panel > Search.
  • Tree (topic) panel. Open any number of distinct topic trees. Add new tree with menu option View > New panel > Tree.
  • Layer info (topic panel). Keep topic map layer info panel open while you edit the topic map. View layer info with menu option View > New panel > Layer info.
  • Drop extractor (topic panel). Yes, Drag and drop extractor is back. Drop extractor is very handy when you need to build a topic of using local resources such as files.
  • Numerous smaller fixes and enhancements.

Looking forward to testing out the new UI features!


New York Times API extractor and Google Maps visualization (Wandora Tutorial)

Tuesday, November 25th, 2014

New York Times API extractor and Google Maps visualization (Wandora Tutorial)

From the description:

Video reviews the New York Times API extractor, the Google Maps visualization, and the graph visualization of Wandora application. The extractor is used to collect event data which is then visualized on a map and as a graph. Wandora is an open source tool for people who collect and process information, especially networked knowledge and knowledge about WWW resources. For more information see

This is impressive, although the UI may have more options than MS Word. 😉 (It may not, I haven’t counted every way to access every option.)

Here is the result that was obtained by use of drop down menus and selecting:

wandora event map

The Times logo marks events extracted from the New York Times and merged for display with Google Maps.

Not technically difficult but it is good to see a function of interest to ordinary users in a topic map application.

I have the latest release of Wandora. Need to start walking through the features.

Wandora 2014-08-20 Release

Wednesday, August 20th, 2014

Wandora 2014-08-20 Release

From the change log:


For a file with the distribution date, in case you have multiple versions, try

In the latest round of new features, Rekognition extractor and Alchemy API image keyword extractor are the two I am most likely to try first. Images are one of the weakest forms of evidence but they still carry the imprimatur of being “photographic.”

What photo collection will you be tagging first?

Wandora Moves to Github

Saturday, July 5th, 2014

Wandora Moves to Gibhub

I saw a tweet today by Wandora announcing a move to GitHub.

From the new GitHub page:

Wandora is a general purpose information extraction, management and publishing application based on Topic Maps and Java. Wandora has graphical user interface, multiple visualization models, huge collection of information extraction, import and export options, embedded HTTP server with several output modules and open plug-in architecture. Wandora is a FOSS application with GNU GPL license. Wandora suits well for constructing and maintaining vocabularies, ontologies and information mashups. Application areas include data integration, business intelligence, digital preservation, data journalism, open data and linked data projects.

If you aren’t familiar with Wandora, check it out.

If it has been a while since you looked at Wandora, its time for another visit.

The traditional Wandora site is still up and news there reports the move to GitHub was to make development more transparent and to attract new developers.

Well, you have the invitation. How are you going to respond?

Wandora 2014-06-05 Available!

Thursday, June 5th, 2014

Wandora 2014-06-05 Available!

From the webpage:

Read carefully Wandora’s system requirements and license before downloading and installing the application. The Wandora application requires Java Runtime Environment (JRE) or Java Development Kit (JDK) version 7. Neither JRE nor JDK is not included in the distribution packages. We emphasize that the Wandora is an ongoing project and the software is incomplete, absolutely contains bugs and the feature set may change without notice. Download Wandora’s latest version (build date 2014-06-05, see Change log):

Of particular interest:

Twitter extractor has been updated to reflect Twitter API changes.


Wandora Bug Fix

Monday, May 5th, 2014

From the change log:


  • Fixes bugs in selection extractors of embedded WWW browser. Wandora used to calculate selection boundaries wrong and wasn’t able to perform selection extractions in the embedded WWW browser.
  • The directory structure extractor, simple HTML list and HTML table extractors now generate more clearer topic maps fragments and links the extraction to the Wandora class. This change hopefully increases the usability of these extractors.

Download the latest Wandora build 2014-05-05.

Wandora – New Version [TMQL]

Tuesday, April 15th, 2014

Wandora – New Version

From the webpage:

It is over six months since last Wandora release. Now we are finally ready to publish new version with some very interesting new features. Release 2014-04-15 features TMQL support and embedded HTML browser, for example. TMQL is the topic map query language and Wandora allows the user to search, query and modify topics and associations with TMQL scripts. Embedded HTML browser expands Wandora’s internal visualizations repertoire. Wandora embedded HTTP server services are now available inside the Wandora application….

Change Log, Download.

Two of the biggest changes:

Download your copy today!

I will post a review by mid-May, 2014.

Interested to hear your comments, questions and suggestions in the mean time.

BTW, the first suggestion I have is that the download file should NOT be but rather wandora-(date).zip if nothing else. Ditto for the source files and javadocs.

A Million First Steps in Topic Maps [318 Example Topic Maps]

Thursday, January 2nd, 2014

A Million First Steps in Topic Maps by Aki Kivela.

From the post:

British Library released images and information from the 17th, 18th and 19th century books under a title “A million first steps”. The information was released as a series of structured text files placed at the GITHUB. The images were stored into the Flickr. License of the images and the information is public domain.

Wandora Team has converted the data files in GITHUB into the topic map serializations. Topic map serializations are XTM 2.0 formatted and can be viewed/edited in many topic map applications such as Wandora and Ontopia. Information has been divided into separate XTM files each containing information about books published during one year. Filename reflects the publishing year. License of the topic map conversions is same as the license of original data files i.e. public domain. Topic map files doesn’t contain actual images or image files but links to images in Flickr.

Information about the used topic map data model:

  • Each book topic has a basename that is a combination of book’s title and identifier.
  • Each book topic has a subject identifier that is derived from book’s identifier. Identifiers doesn’t resolve.
  • Each book topic has an English display name that is book’s title.
  • If book has a Digital Service Library identifier, it is attached to the book topic as an occurrence. Also, PDF link to the book is attached to the book topic as a separate occurrence.
  • If book has an Ark id, it is attached to the book as an occurrence.
  • Author topic is associated with the book topic.
  • Publication date topic is associated with the book topic.
  • Image topics are associated with the book topic.
  • Place of publishing topic is associated with the book topic.
  • Image topic has a subject identifier and a subject locator that resolve original image file in Flickr.
  • Image topic has a basename that is image’s identifier.
  • Image topic has occurrences for the image number, the page number and the volume number.

What can be done with the topic map conversions of the “Million first steps”? Next chapters describe some ideas.

Wandora and other topic map applications can provide a nice viewer for the book data and especially images. Topic map applications can also provide alternative publishing options that create a WWW site or a specific visualization out of the topic maps.

The user can easily enrich the information captured into the topic map, either manually or semiautomatically. A topic map is fundamentally a graph and topic map applications contain powerful tools to alter and modify the graph. Also, topic maps are incremental and two or more different topic maps can be merged. This enables linked data type merging of book information with some other information sources. Wandora has over 50 different information extractors.


Download XTM conversions of the Million first steps (26.8 MB).

If you have been looking for example topic maps, here are three hundred and eighteen (318) of them. Not every year has a topic map in case you are wondering about the missing years.

Kudos to the Wandora team for splitting the topic maps by year of publication of the books containing the images!

Library interfaces often enable date range searching and that will help identify other materials to associate with the images in question.

Not to mention that annotating images from a particular year will make it easier to make a noticeable impact on the starting topic map.

So, which year are you going to take?

I was going to pick 1611 because of the King James Bible but interestingly, there appear to be no entries for the KJV in that year.

Will have to look around the images at Flickr and pick another year.

Wandora – New Release 2011-12-07

A new release of Wandora is out!

I haven’t tested the new features but I am sure the project would appreciate any comments you have.

Some early remarks:

The “version” of Wandora should appear in the file name, which would be helpful for those of us with multiple versions on our hard drives.

There should be more detailed release notes, for bugs as well as new features.

I may be overlooking it but if a formal bug/feature tracking system is being used (other than the forum), it would be useful to have at least a read-only link to that tracking system.

Wandora – New Release

Monday, September 19th, 2011

Wandora – New Release

New Features:

  • Fixes GeoNames extractors. Now Wandora’s GeoNames extractors require a username provided by the GeoNames.
  • R console window has been rewritten.
  • Topic table allows any topic selection now. Java’s JTable component allows selections of single rows and single columns only (which is fine if you have only one column). Now Wandora overcomes the default limitation.
  • Occurrences can be duplicated (to other type). User can also change occurrence’s type.
  • We have tested Wandora on Java 7.
  • New feature: Export similarity matrix. Similarity matrix is similar to topic adjacency matrix but matrix cell contains a value representing selected similarity of row and column topics. Feature has predefined similarity measures of Subject locator similarity, Highest subject identifier similarity, Basename similarity etc.
  • Wandora’s Firefox and Thunderbird plugin works now on FF version 6.0 and TB version 6.0.

Random Graphs Anyone?

Friday, July 22nd, 2011

I saw a tweet from @CompSciFact (John Cook) pointing out Luc Devroye’s (McGill University) Non-Uniform Random Variate Generation (Springer-Verlag, New York, 1986) was available for free download.

Amazon lists used copies starting at $180.91 and one new copy for $618.47, so you are better off with the scanned PDF, unless you are simply trying to burn up grant funding before the end of a year.

Chapter XIII. RANDOM COMBINATORIAL OBJECTS includes random graphs and notes:

Graphs are the most general comblnatorlal objects dealt wlth In this chapter. They have appllcatlons In nearly all flelds of sclence and englneerlng. It is qulte impossible to glve a thorough overvlew of the dlfferent subclasses of graphs, and how objects In these subclasses can be generated uniformly and at random. Instead, we will just glve a superflclal treatment, and refer the reader to general principles or speclflc artlcles In the literature whenever necessary.

For one use of random graphs in topic maps work, see the Random Graph Generator in Wandora.

Wandora – New Release

Thursday, March 31st, 2011

Wandora – New Release

Latest new feature:

GATE (General Architecture for Text Engineering) is a mature and actively used software framework for computational tasks involving human language. GATE has been developed in The University of Sheffield. It is open source and free software. ANNIE (A Nearly-New Information Extraction System) is a component of GATE used for information extraction. ANNIE extracts information out of given unstructured text. Wandora features a tool called GATE Annie that uses GATE and ANNIE to extract topics and associations out of given text, an occurrence for example. Tool locates in Wandora application menu File > Extract > Classification. It is also available in occurrence editor and browser plugin.

GATE and ANNIE are included in Wandora distribution package and embedded tool GATE Annie processes given text locally.

See: for more details.
