NDH-compatible
KLEKSI meets the conditions that Network Digital Heritage (NDH) sets for an NDH-compatible collection registration system.
On this page we would like to explain to you how you can meet these conditions with the help of KLEKSI.
Work NDH-compliant and reach more audiences with your heritage collection
In order to be NDH-compatible, a collection registration system must meet the standards and requirements set by the Network Digital Heritage. In order to be able to work NDH-compatible, agreements have been made with heritage organisations, software suppliers and other partners in the network in recent years to connect heritage in an even better way. KLEKSI meets all the conditions set by NDH. This means you:
- Uses sustainable identifiers and thus avoids the well-known 404 message;
- Links to URIs of standardized terms via the Terms Network;
- Heritage information publishes as linked (open) data;
- makes datasets findable for others via the Dataset Register;
- Use IIIF to access image collections.
Below we would like to explain to you how these components are processed in KLEKSI and what benefits this has for your organization.
Your digital object is always available online at the same location
With the help of a sustainable persistent identifier, your digital object always remains available online at the same location.
It is important to prevent link rot, i.e. when a clicked link no longer works, when making and keeping digital collections accessible. This is addressed with a durable persistent identifier (PID). This means that digital objects always remain available online at the same location.
KLEKSI generates its own PIDs (klek.si) and also supports PIDs from the Handle System. In KLEKSI you can generate a site bundle zip file for Handle.net, which then needs to be uploaded once to Handle.net. After that, a unique PID is automatically generated for each description or object.
Linking to URIs of standardized terms via the Terms Network
Users want to be able to find digital heritage as easily as possible. As a collection manager, you must provide your material with unambiguous terms. KLEKSI is linked to the NDE Term Network. KLEKSI has an (API) link to the NDE Term Network in the Netherlands. Every word you enter can be searched via the Term Network in all existing thesauruses, such as RKDartists, GTAA, Wikidata or AAT. The system then shows all results found and per result you can see which definition, alternative terms and broader or narrower terms belong to it, with the corresponding link to the relevant information. You can make your own choice and link the term that fits best with 1 click. It is possible to link other thesauruses for you in addition to the Termennetwork. For predicates there is a link with Dublin Core, Schema.org and Europeana.
Publishing heritage information as linked (open) data
Linked (open) data is a standard for linking information and sharing it with the rest of the world. What can you achieve with it as a heritage institution? Heritage institutions manage a wealth of information. More and more of them are digital and available through their own websites. These digital collections become even more usable if the information is interconnected. Users will then no longer be bothered by boundaries between collections, institutions or sectors. They can find all relevant information together to answer questions about the 'who, what, where and when'. For example, all together about Rembrandt, about water mills or about a monumental building. Using linked data makes this easier. That is why this is the appropriate technique to increase the usability of digital heritage collections.
Linked Open Data (LOD) is created by KLEKSI by publishing structured data to the web, using standards such as RDF and SPARQL to interconnect and make it accessible to various applications and systems.
Making datasets findable for others via the Dataset Register
The dataset register provides insight into the availability of datasets in the heritage field and thus stimulates the use of these datasets. Describing a dataset shows great similarities with describing a heritage collection. It is therefore logical to also manage the datasets via KLEKSI. Close to the source, because the datasets (as a file or as an API) are often also made available from here. Online publication of the dataset descriptions is therefore often a simple and above all automated step.
The purpose of the Dataset Register is to gain insight into heritage datasets. In KLEKSI you can create, describe and publish your own datasets. You can indicate yourself whether you want to add the URLs of the dataset descriptions to the Dataset Register. This creates a complete overview of available datasets.
KLEKSI uses IIIF to access image collections
KLEKSI uses the International Image Interoperability Framework (IIIF) to provide seamless and advanced access to digital image collections. This allows you to benefit from several advantages:
- Flexible viewing and interaction : IIIF allows you to view images in a flexible way and enable interaction with these images. Users can zoom, pan, rotate and perform other interactive actions, creating a rich viewing experience.
- Unified access : IIIF allows you to present footage from different sources in a uniform way. This means that users can easily switch between different collections and platforms without being limited by the technical specifications of each individual source.
- Deeper integration and enrichment : IIIF allows images to be integrated with additional contextual information, such as transcripts, annotations, and metadata. Thus, with KLEKSI you can enrich the image collections with rich information, enabling researchers and users to conduct more in-depth investigations.
- Collaboration and reuse : IIIF is an open standard supported by a growing community worldwide. IIIF makes it easy to share images with other institutions and platforms that are IIIF compliant. This promotes collaboration and stimulates the reuse of digital collections.
In short, IIIF provides an improved user experience, enables uniform access to various collections, enables deeper integration of contextual information and promotes collaboration and reuse of digital image collections.
Our target audience
KLEKSI is intended for museums, heritage institutions, foundations, associations and collectors who want to archive, document and digitize their collection. KLEKSI offers a simple and flexible dashboard that allows you to manage your collection(s) very easily and quickly.
