Updates on VisITMeta and irondemo

Just a few days after the last release, we like to introduce VisITMeta 0.1.2 to the public.

Changes and new features include

  • Bipartite layout: identifiers and metadata are ordered in 5 columns, where columns 1 and 5 are used by metadata attached to one identifier, column 3 is used by link metadata and columns 2 and 4 are used to show identifiers.
  • Dataservice uses neo4j v2.1.2 instead of v1.8
  • Extended identifier now uses the root-element of their inner XML to represent them
  • Metadata nodes now also allow different textual representation (two supported styles at the moment: just the typename of the metadatum, or with the publish timestamp in a second text line)
  • Transparency of glow effects now works correctly
  • Fixed a bug that occured when the liveview-checkbox was unchecked too soon after application startup

alternate text This screenshot shows the new bipartite layout as well as some of the features from version 0.1.1, like enhanced identifier information or the new information panel at the bottom of the GUI.

Furthermore, we released version 0.4.5 of our demonstration environment irondemo. It features a new scenario visitmeta-project as well as some bugfixing/enhancements to the agenda parser (now allows trailing/leading whitespace and blank lines).

Both projects are available via their repositories on Github.

VisITMeta 0.1.1 released

We’re proud to announce the release 0.1.1 of our IF-MAP visualisation tool VisITMeta.

Changes and new features (since version 0.0.5) include

  • Now using ifmapj v2.2.0.
  • Support for external motion control devices; a (simple) integration of the LeapMotion device for control via hand and gesture recognition was also released as a separate project. Check the Readme-file of that project to see how you can build and integrate it within the VisITMeta visualization application.
  • Identifer nodes now show more information directly, i.e. IP addresses now state ip-address: 10.0.0.1 (IPv4) instead of just ip-address.
  • Identifier nodes can be colored according to their type.
  • Further information about identifier and metadata is now shown via a extra subscreen on the bottom instead of a tooltip.
  • Fixed a severe bug inside the dataservice application.

Trust@HsH participates at TCG Members Meeting 2014 in Barcelona

The triennially hosted members meeting of the Trusted Computing Group (TCG) is the place for planning and coordinating the tasks and activities within the workgroups of the TCG and a great opportunity to bounce off ideas with talented infividuals from both industry and academia.

Leonard Renners and Thomas Rossow from the Trust@HsH research group participated in this year’s June meeting that was held in Barcelona from 24th of until 26th of July. They endorsed the new developments within the Trust@HsH group (e.g. in the SIMU and VisITMeta research project) and contributed to discussions about the future of the IF-MAP and TNC specifications.

They were also happy to have fruitful and interesting conversations with some of our long-time partners within the TCG such as Liza Lorenzin (Juniper Networks), Steve Hanna (Infineon), Andreas Steffen (Hochschule für Technik Rapperswil) and Henk Birkholz (Fraunhofer SIT).

A Change in Leadership

Trust@HsH group founder and former group lead Prof. Dr. Josef von Helden has been elected for the office of president of the University of Applied Sciences and Arts, Hanover and has taken office on May, 12th (see official press release). As a consequence thereof, he unfortunaltey had to resign as the group lead of Trust@HsH.

Luckily, with Prof. Dr. Volker Ahlers, Prof. Dr. Felix Heine and Prof. Dr. Carsten Kleiner as new group lead and Leonard Renners as an additional research associate in the SIMU project, the Trust@HsH is stronger in members than ever before and eager to tackle new scientific challenges.

We wish Prof. Dr. von Helden good fortune for his new assignment and may he lead the univiersity with the same passion, commitment and aptitude that he has built up and managed the Trust@HsH group.

alternate text

The Trust@HsH research group participated for the third time in a row at the TNC Spring Plugfest 2014, which was hosted by Fraunhofer SIT in Darmstadt, from April 1st till April 3rd. At the event we had the chance to test the interoperability of our latest IF-MAP software components with the components and products of other TCG members.

We basically tested our ifmapj-based MAP clients and our MAP server irond in their latest version, as well as a few yet unreleased components.

Thanks to Ronald Marx and the team from Fraunhofer SIT and Matt Tracy from the Trusted Computing Group for organizing and hosting the event.

Please also have a look at the news on the plugfest at the SIMU project site.
