+                  associated with data carriers. Around the middle of the 6th century BC Croesus, the King of
+                  Lydia, minted his heraldic animals on standardized gold and silver blanks (<ref type="graphic" target="#abb01">Figure 1</ref>). This procedure
+                  initiated the era of coins as a currency. However, Croesus had not only created a
+                  means of payment, but also a data carrier, which contained information on the
+                  wealth or the geographic range of influence of a certain regime.</p>

+               <p>Especially for archaeologists, coins are an ideal supplier of information. They
+                  enable the dating of an excavation layer, give evidence of trading connections and
+                  the political and economic conditions of a certain period. However, these data
+                  carriers used for thousands of years are increasingly disappearing from everyday
+                  use in the living presence. With digital payment methods, there is hardly any use
+                  for coins anymore. A millennia old cultural practice seems to approach its
+                     end.<note type="footnote"> In Belgium, cent amounts are rounded to 5-cent
+                     multiples in retail since December 2019, so that one- and two-cent pieces are
+                     virtually no longer in circulation.</note>
+               </p>
+               <p>However, payment transactions are only one field in which currently the exchange
+                  of information runs almost only digitally. As comfortable as the new, electronic
+                  forms of communication are for humankind living today, it remains unclear how
+                  information of our era will be usable in the long term. To interpret the cuneiform
+                  on a clay tablet, the hieroglyphs on a stone stele or the ancient Hebrew on a
+                  scroll, one must only know the respective writing system to be able to read it.
+                  But when it comes to reading a digital document one must not only provide the
+                  electronic hardware but also the matching software to simply make a text visible
+                  at all. </p>
+               <p>The transmission of our current knowledge to future generations is thus
+                  inseparably linked with electronic technology&#160;– and thus with the risk of being
+                  lost. The development of digital media shows how real and inherent this danger is.
+                  Who can run a floppy disk or a VHS video cassette today? With every transfer of
+                  data to a new medium, parts of information get lost. Around 400 AD a similar media
+                  change seems to have been one of the causes of the so-called ›loss of books in
+                  late antiquity‹ when bound codices of parchment replaced scrolls of papyrus.
+                  Thereafter 1,400 years had to pass until modern libraries had again comparable
+                  stocks as they are recorded for ancient libraries.</p>

+               <p>In the case of digitally stored data, there is another threat of loss that results
+                  from the programs with which the data is stored. Specialized software can often
+                  only be used with fixed-term licenses. If users do not have the corresponding
+                  license (anymore), the data is unreadable to them. The same applies to the further
+                  development of software. Due to the progress and development of programs, it is
+                  possible that data records cannot be opened only a few years or updates after they
+                  have been saved. Datasets that are not worked with, maintained, used or changed,
+                  are in danger of becoming lifeless mummies in digital sarcophagi, of which it is
+                  uncertain whether they can ever be recovered again.</p>
+               <p>In this regard, the very technical progress and digital development to store data
+                  generates gigantic centrifugal forces and corrosive powers that threaten the
+                  continued existence and further usability of records. Since these relationships
+                  are inherent to the system, it is important to look for ways to prepare
+                  information in such a way so that it can react as flexibly to these developments
+                  as possible and remain accessible for as many users as possible. </p>
+               <p>In awareness of these challenges, the De Jonge Wiki was created as a prototype to
+                  prepare data according to certain specifications. As medium of choice, a freely
+                  accessible online database with English as operating language was selected, to be
+                  easily accessible for interested users. As a software, the open source and cost
+                  free products <ref target="https://www.mediawiki.org/wiki/MediaWiki"
+                     >MediaWiki</ref> and the potent extension <ref target="https://wikiba.se/"
+                     >Wikibase</ref> of the <ref target="https://wikimediafoundation.org/">Wikimedia
+                     Foundation</ref> were chosen. This selection offers the advantage that the
+                  required functions are tested, stable, and established by the daily use of
+                  millions of users of the Wiki community.</p>
+               <p>MediaWiki software has a routine update path with only a few disruptive changes.
+                  In addition, there are a number of ways to export to a wide variety of formats,
+                  which is beneficial to the integrity and extensive use of the data. Furthermore,
+                  there is the potential for communication and automated alignment with similarly
+                  designed databases. Another important aspect is that other organizations that are
+                  interested can adopt and adapt the data management structure used here for their
+                  own projects. </p>
+               <p>Since April 2021, the De Jonge Wiki has been developed as part of a cooperation of
+                  the EU-funded PALAMUSTO project (Grant Agreement ID: 861426) with the Institute of

+                           >Figure 3</ref>) was a fitting choice for a case study because it is both
+                        well studied and of a manageable scale. The first mention of a castle in
+                        Heverlee dates back to 1371, although a fortified building can be assumed to
+                        have existed for centuries before that. The donjon of which we know from
+                        pictorial representations seems to have been built in the first half of the
+                        15th century under Raas van Graven or Antoine I de Croÿ.<note

+                        The decisive expansion into a representative hunting lodge happened under
+                        William de Croÿ, probably between 1505 and 1520, when the southern wing with
+                        the two corner towers and significant parts of the western wing were built.

+                     <p>Because of this, the second main concern of the project was to strive for a
+                        user interface based on Wikipedia, so that users will be spared the anxiety
+                        threshold of the new and unknown. Instead they should be able to move in an
+                        environment where design and functions are known to them from their daily
+                        use of Wikipedia. To achieve this goal, it was obvious to use MediaWiki, the
+                        same software with which Wikipedia is operated. In addition, it also offers
+                        all opportunities for joint editing and documentation of editorial changes
+                        that are offered by Wikipedia as well. It can thus be used as a <term

+                        the exchange between the different researchers involved. First projects with
+                        students also showed that the infrastructure of the De Jonge Wiki is
+                        particularly well suited for <term type="dh">Peer Assisted Learning</term>
+                           (<term type="dh">PAL</term>) in academic education, where students support
+                        each other with their respective skills in mastering a task. Another
+                        advantage of using an established software ecosystem is the variety of
+                        additional tools and functionalities, for example the accessibility for
+                        users with disabilities and their tools such as screen readers.</p>
+                     <p>An additional benefit of using Wikimedia Foundation software is the
+                        possibility of linking to other platforms besides Wikidata and Wikipedia,
+                        such as <ref target="https://commons.wikimedia.org/wiki/Main_Page">Wikimedia
+                           Commons</ref>. In this media repository, free-to-use images, sound
+                        documents and videos as well as other media such as 3D objects can be
+                        published. In digital infrastructures, which are based on Wikibase or
+                        MediaWiki as software, these media can be integrated as preview images by
+                        simple linking, while hosting and all related activities are taken over and
+                        provided by Wikimedia Commons. This not only has the advantage that the
+                        hosting is outsourced, but also that the media in question can also be found
+                        in an environment used by a wider public.</p>
+                     <p>Due to the limited options for displaying 3D objects on Wikimedia Commons,
+                        three additional methods for embedding 3D files via <term type="dh"
+                           >iframes</term> were tested. Firstly, <ref
+                           target="https://sketchfab.com/">Sketchfab</ref>, which proved to be
+                        technically straightforward. However, being a software from a commercial
+                        provider, this solution does not align with the <term type="dh"
+                           >FAIR/O</term> principles and can only be used as a temporary solution.
+                        Therefore, for future integrations of digital 3D models as iframes, the use
+                        of the <ref target="https://kompakkt.de/home">Kompakkt</ref> platform is
+                        planned. Kompakkt is an extension of the e-learning software ILIAS developed
+                        by the Department of Digital Humanities at the Faculty of Arts and
+                        Humanities of the University of Cologne. Another option is Semantic
+                        Kompakkt, a technical advancement of Kompakkt developed within the
+                        NFDI4Culture initiative.<note type="footnote"> Cf. <ref type="bibliography" target="#nfdi_semantic_2023">Semantic Kompakkt 2023</ref>.

+                        of 3D models, and similarly to the De Jonge Wiki it uses Wikibase for
+                        processing statistical data. However, experiments in collaboration with
+                        Lozana Rossenova from the Technische Informationsbibliothek (TIB) in Hanover
+                        showed that using this infrastructure would have only made sense if Semantic
+                        Kompakkt had been implemented in the logic of the Wikibase records from the
+                        beginning of the De Jonge Wiki project. Nonetheless, this option presents a
+                        promising possibility for future projects.</p>

+                     <p>Basically, it can be said that there are several options when creating a

+                           >RDBMS</term>), in which entities are assigned different properties, in
+                        the style of different columns in tables. On the other hand, there are graph
+                        databases in which information is stored as knowledge graphs, that means as
+                        different entities that can be linked to one another by properties. One
+                        possible concept for such graph databases are <term type="dh">Labeled
+                           Property Graphs</term> (<term type="dh">LPG</term>), which means that the
+                        connection between certain entities is expressed in main properties which
+                        are attached to a node and additional simple key–value pairs: <quote>Lauren

+                        structured database with a hierarchy or taxonomy. In this case, the entire
+                        complex of the castle with its topography and all associated architectural
+                        facilities is defined as the highest level. The initials AC for Arenberg
+                        Castle as part of their name mark all elements that are components of this
+                        complex. The main buildings of the castle are referred to by the initials MC
+                        for Main Castle. This Main Castle is in turn divided into the various wings
+                        and construction volumes, each defined by initials, such as for example EW
+                        for the East Wing. These wings again consist of different floors as well as
+                        facades and roofs, such as the first floor expressed as 1F. At the lowest
+                        level are the individual rooms designated by the currently used room

+                        both as a MediaWiki file and as a connected Wikibase file. In the MediaWiki
+                        entry, the information is published as text and images in the style of
+                        Wikipedia and&#160;– if possible&#160;– gives an overview of the findings to the
+                        respective building history. In the Wikibase entry, however, statistical
+                        information is stored in the form of RDF knowledge graphs. </p>
+                     <p>These relationships are modelled according to a defining system, a so-called
+                        ontology, as for example CIDOC CRM (Comité International pour la
+                        Documentation Conceptual Reference Model). In a database, an ontology forms
+                        the intended frame of reference, which is then filled with the contents of
+                        the respective data records. The Wikibase datasheets of the De Jonge Wiki
+                        are based on the ontology on which also Wikidata is based. This decision was
+                        made, on the one hand, because this type of data modelling is applied by an
+                        influential and internationally accepted structure as Wikidata and, on the
+                        other hand, because this ontology is not a rigid and hierarchical taxonomy,
+                        such as CIDOC CRM, but flat and flexible and can be adapted to the
+                        requirements of the respective records. This makes it easily possible to

+                        the FAIR/O principles: Findable, Accessible, Interoperable, and Reusable
+                        with the help of free Open license software. By adopting the digital
+                        infrastructure developed as a prototype, other scientific projects or
+                        cultural organizations can prepare their data effectively and valuable and
+                        make it publicly accessible in a user-friendly way.</p>

+                     <head>2.4 Open Questions and Challenges</head>
+
+                     <p>Fortunately, when the basic considerations were implemented in a functioning
+                        database, all of the intended aspects could be set up without major
+                        problems. When the data was entered by student research assistants, it was
+                        found that the structure can be understood intuitively after a short
+                        briefing. This made it possible that the student research assistants could
+                        follow the underlying logic intuitively and suggest and implement their own
+                        additions in order to optimize the database. In practice,
+                        however, there were also some challenges that could not be optimally met
+                        within a very limited time and budget framework. </p>
+                     <p>Even at the beginning of the implementation, it became clear that the web
+                        space, which was kindly provided by KU Leuven, did not enable an easy way to
+                        use the Docker version of Wikibase. This is mainly due to the fact that the
+                        University is primarily interested in protecting its own research
+                        achievements from access by third parties. A classic virtual machine (VM)
+                        service operation as an execution environment for Docker or other container
+                        systems was classified as too vulnerable in regard to data security.
+                        Therefore some practical additional services such as the <ref target="https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual">›Query Service‹</ref> are not yet available at the De Jonge Wiki. This
+                        would have offered a simple, user-friendly possibility to design queries in
+                        the <ref target="https://www.w3.org/TR/sparql11-query/">SPARQL</ref>
+                        scripting language via the dataset in Wikibase, as well as the graphic
+                        representation of these search results. In addition, overview pages cannot
+                        simply be generated in this way, for example a list of all items that are
+                        identified as rooms (Property:P2 ›instance of‹; Item:Q257 ›Room‹). In order
+                        to still be able to have a classification, the articles in the frontend must
+                        be tagged and marked in accordance with the categories in Wikibase. This
+                        requires a double administration, which may eventually result in
+                        inconsistent information.</p>
+                     <p>The fact that Docker cannot be used also means that software updates have to
+                        be installed manually with more effort, which is why a certain amount of
+                        expert knowledge is required in dealing with MediaWiki software. However,
+                        administrators often have experience in using these solutions, especially at
+                        universities which provide wikis to support teaching, and should therefore
+                        be able to cope with this challenge. The De Jonge Wiki is in the process of
+                        moving to an environment in summer 2023 where Docker and SPARQL queries can
+                        be used and where the data will be backed up on a local server for improved
+                        security.</p>
+                     <p>Another unavoidable issue is that the datasets are not perfectly uniform
+                        because of the human factor, as several employees work on the same datasets
+                        in different daily conditions. These inconsistencies would also have been
+                        easier to identify and fix if certain Wikidata approaches had been
+                        integrated into the project; among other things, the query service, but also
+                        restrictions on property fields or shape expressions would have been valid
+                        approaches to reduce these problems, but have not yet been implemented.<note

+                        for both namespaces of the wiki has not yet been completely standardized and
+                        only works in a case-sensitive manner.</p>
+                     <p>It should also be emphasized that the software of the Wikimedia Foundation

+                        protection for article pages. With the sites of individual files such as the
+                        images uploaded in the wiki, this function does not exist.</p>

+
+                  <p>With the De Jonge Wiki, for the first time a user-friendly frontend based on
+                     MediaWiki was linked with a semantic database based on Wikibase with the help
+                     of a simple template, as was previously only implemented for the exchange
+                     between Wikipedia and Wikidata. When working with students, it became clear
+                     that these structures could be understood quickly and that it was possible to
+                     deal with them independently after a short introduction phase. The
+                     infrastructure tested in this project therefore has the potential to be used by
+                     organizations such as museums as an up-to-date tool for inventorying and
+                     documenting measures following the FAIR/O principles. </p>
+                  <p>Using MediaWiki and Wikibase as software results in two further advantages. On
+                     the one hand, it is popular, long-lasting software that can be used free of
+                     charge and does not require licensing. One has to be aware however that the
+                     term ›long-lived‹ is very relative in the world of modern data sciences, since
+                     this kind of wiki system itself has only been in existence for a little over 20
+                     years.<note type="footnote">Cf. <ref type="bibliography" target="#wikipedia_history_2023">History of Wikis 2023</ref>.</note> On the other hand, the data records created in
+                     Wikibase can be read automatically and integrated into other databases. In this
+                     context, it must be noted that the De Jonge Wiki will only be searchable
+                     together with other Wikibase databases in common SPARQL queries after the
+                     forthcoming move to a new hosting. However, this is due to the hosting in the
+                     digital infrastructure of KU Leuven and can easily be avoided in the case of
+                     any similar projects.</p>
+                  <p>The De Jonge Wiki is already proving to be a welcome opportunity to convey
+                     content. In the academic year 2021/2022, the data was used by the RLICC at KU
+                     Leuven for the training of master’s students in the modules ›Analysis,
+                     Registration and Documentation Techniques: ArchDOC‹ (H00W6A), ›Building
+                     Archeology: Integrated Project Work‹ (H01X8A) and ›Integrated Project Work 3‹
+                     (H00X2A). In addition, as part of the Master of Digital Humanities training at
+                     KU Leuven, a collaboration with Prof. Andrew Vande Moere from the research
+                     group ›Research[x]Design‹ (RxD) took place in the study year 2021/2022,
+                     which deals with digital designs to convey and develop the Arenberg Castle.
+                     Within this project, the master students used the De Jonge Wiki for their
+                     research.<note type="footnote">Cf. <ref type="bibliography" target="#vandemoere_rxd_2023">Prof. Andrew Vande Moere 2023</ref>.</note> At the LMU in Munich, the De Jonge Wiki served as
+                     central example in the seminar ›Renaissance-Architektur digital. Aktuelle
+                     Forschungen und ihre Unterstützung durch semantische Datenbanken‹ (09523)
+                     during the winter semester 2021/2022 by Prof. Stephan Hoppe. There, students
+                     edited their own content in the database.<note type="footnote">Cf. <ref type="bibliography" target="#lmu_renaissance_2023">Renaissance-Architektur digital 2023</ref>.</note> With Frieder Leipold and Max Kristen as members,
+                     the De Jonge Wiki is meanwhile also represented at the international <ref
+                        target="https://wbstakeholder.group/members#individual-members">Wikibase
+                        Stakeholder Group</ref>.</p>
+                  <p>With the De Jonge Wiki, a database was created that can be used intuitively to
+                     move freely in a virtual castle and get detailed information on the building
+                     history. Another requirement was the possibility to save data records in the
+                     background in a semantic database that meets current international standards.
+                     These tasks have been accomplished convincingly. </p>
+                  <p>Organizations or projects that are interested in the De Jonge Wiki as a
+                     prototype for scientific databases can find detailed information on the
+                     extensions and skins used in the online reference list <ref
+                        target="https://wikiapiary.com/wiki/DeJongeWiki">WikiApiary</ref>. More
+                     information on the structure and logic of modeling the data can be found on the
+                        <ref

+                     prototype tested here could be used for similar databases as their digital
+                     infrastructure.</p>
