Trezorix provides infrastructure based on the Reference Network Architecture (RNA). An RNA environment is used for building semantic networks, in wich content items (units of information, like articles or database records) are linked via concepts (units of meaning, like keywords).
RNA environments serve as a retrieval layer, placed between knowledge sources (like file systems, databases, et cetera) and end user applications (like websites). Each RNA environment contains a number of tools, the RNA Toolset, for easy setup and maintenance of semantic networks.

Dutch mills in the picture
04-06-2011 When you think of the Netherlands, you think of mills. Our country has almost 1300 wind and water mills that are designated cultural heritage. The Dutch National Cultural Heritage Agency (RCE) and partners in the milling sector are working on a reference network to make these monuments available online. In addition to geographic data for presentation on digital maps the data about the mills in the reference network is enriched with information from various different reference structures, such as mill types, functions and parts. These structures are made up of the International Milling Society's Dictionary of Molinology and the Dutch Milling Dictionary. The Mill project is part of the RCE Semantic Network, driven by an RNA-environment.

Collections allied
06-05-2011 "Before long we won't be a museum with a network anymore, but a network with a museum." With this device of colleague-institution Naturalis in mind, the Army museum took a big leap forward in 2010 in the developement of its "Allied Collections". In this project, funded by the Dutch Ministry of Economic Affairs, ten of the museum's digital collections are interrelated with the use of several thematic thesauri. Also the Army museum will soon offer the possibility to identify the regiment, rank and position of (pictures of) old uniforms making use of facet determination. Annet Ruseler, Head of Collection Information of the Army museum wrote an article about the project in ICOMAM magazine. Read the entire article here. The search portal and facet determination tool will be made available in the second quarter of 2011.

Acheological finds charted
18-04-2011 Archaeologists and excavation workers regularly stumble upon the traces that people, animals and plants left on Dutch soil in the course of history. All these bottom finds are thoroughly catalogued by the Dutch National Cultural Heritage Agency (RCE) in three databases, that contain archeological, archeozoological and archeobotanical finds. The Archeologie in de Gemeente (archaeology in the municipality) project gives an overview of these. The finds, enriched with all kinds of data from the Archaeological Basis Register (ABR, archaeological authority lists, see below), are presented on a geographic map, combined with a practical timeline. These enable users to search for finds on specific locations and from a particular period (link). The project is part of the RCE Semantic Network, driven by an RNA-environment. The end-user application is developed by Infoprojects.

Archaeological thesauri
14-03-2011 City archaeologists, universities, archaeological companies, all use the Archaeologisch Basis Register (ABR, archaeological authority lists). This collection of ten reference structures (thesauri) offers standardized codes for recording data on archaeological finds, such as materials, archaeological periods, cultures and complex types (types of sites). The Dutch National Cultural Heritage Agency (RCE), manager of ABR, makes these reference structures available online. The use of an RNA environment enables RCE and partner organisations to interlink their archaeological data through these thesauri and make them retrievable on the internet.

Online birdwatching
01-03-2011 After two and a half years of pioneering STERNA is completed. The international project initiated by Naturalis and Trezorix concluded with a meeting in Leiden where the best-practices were evaluated and recommendations for future projects were formulated. The result: well over 200.000 digital objects about birds from all over Europe semantically enriched and interrelated by a multitude of knowledge structures. Using the RNA interface developped by Trezorix, four portals offer access to this content in various languages, each presenting a different view on the collections. In addition parts of the content in STERNA have been harvested by Europeana and made available through the portal of that project. With these achievements STERNA has amply met its primary targets.

Exploring the Dutch natural history collections
04-02-2011 Visitors of a natural history museum usually get to see only a tiny part of the total number of collection objects owned by the museum. The rest is savely stored behind bolted doors. Natuurcollectie.nl is going to change all that. In this project the Dutch natural history museums collaboratively put large parts of their collections online. By making use of the possibilities offered by Trezorix's RNA architecture and RNA Toolset, these collections are integrated and can be searched through from different angles. For instance several different, semantically linked taxonomic systems are used together to indicate the place of the object in the animal, plant or fungi kingdom. You can start your quest for Dutch natural history objects at www.natuurcollectie.nl. Natuurcollectie.nl is a follow-up the DNCN-project. Read more...

Trezorix for Sterna to the US25-04-2010 Every year another city in the United States is host to the Museums and the Web conference, which is the meeting venue for digital heritage professionals. During this three-day event all sorts of innovative online applications by and for museums and other knowledge institutions are presented. This year the conference was held in Denver and Trezorix was there. During the exhibition Sterna partners Trezorix, Naturalis and Salzburg Research introduced the new Sterna environment, the first to use version 4 of the RNA Toolset. New features are facilities for highly flexible data modelling, an update agent that can import changes in external resources automatically into the RNA environment, and improved import of complex datasets in the form of tables. All this, and of course the possibility for integrating multilingual content that has always been one of the key features in the RNA Toolset interested many conference visitors - not surprising given the international character of the event: museums, companies and government agencies from twenty-five different countries were represented in Denver.

Teylers Museum integrates six collections
10-12-2009 A man of the Age of Enlightenment, Pieter Teyler van der Hulst (1702-1778) put together a broad collection of art and scientific objects. This collection, which is maintained and extended by the Teylers Museum since 1784, consists of six subsets: art, rare books, numismatics, scientific instruments, palaeontology and mineralogy. Currently these are being integrated into one findability layer, based on Trezorix' RNA architecture. The subsets are searchable as if they are one collection, until recently an impossibility due to differences between management systems and the various data models. Three of the sets, containing about 70.000 items which are composed of more than half a million RDF objects, are already integrated in the findability layer. Read more...

A network of animals and plants
31-12-2009 The Dutch Species Catalogue is a treasury of information about the more than 35000 plants, animals and fungi that have been spotted in the Netherlands since 1758. The site, which is an initiative of Naturalis and the Dutch Ministry of Agriculture, Nature and Food Quality, has been realised since its start years ago in cooperation with Trezorix. Recently a completely renewed version went online. The RNA Toolset is used for production and maintenance of the complex taxonomic structures of the Species Catalogue, and for presentation and monitoring of the variety of information provided by the partner organizations managing biodiversity data. Fabrique, our opposite neighbour in Delft, did the interface design of the new site. Read more...

What kind of longicorn is this?
08-12-2009 People who want to know what kinds of longicorns are crawling about their backyard can now visit Naturalis. Online that is, because the Dutch national museum of natural history has recently launched a website on which visitors can identify longicorns. With this digital determination system users can randomly select recognizable features, a process that is supported with imagery. Eventually they will end up with the right longicorn. The determination system is one of the results in the Facet Determination project, in which Naturalis and Trezorix have developed tools and workflows to create digital determination sets based on spreadsheets. The tools and workflows are designed in a way that their employment is not restricted to the domain of natural history. The Dutch Army Museum will offer the system to her online visitors for determination of uniforms. Read more...

Green light for Allied Collections
01-12-2009 Over the past years the Army Museum in the city of Delft has invested considerably in the digitization of its collection. This digital treasury contains many heterogeneous resources that together give a detailed account of the Dutch military history. Currently however only a small part of these resources are made available online and the connections between the various different items are hardly visible. To improve this the Dutch Ministry of Economic Affairs has recently granted a subsidy to the museum for the realization of the Allied Collections project. In this project nine digtal collections will be brought togehter in an RNA environment, so end-users can search and use them in an attractive and coherent way. Read more...
