urn:cts:humboldtdigital:about.H0021024:1.3.2	p	The metadata and texts of the edited manuscripts (travel journals, letters and documents) are encoded according to the guidelines of the <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://www.tei-c.org/ns/1.0">Text Encoding Initiative (TEI)</ref>. By using ediarum.BASE.edit, the <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://deutschestextarchiv.de/doku/basisformat/">Base format of the German Text Archive (DTABf)</ref> (<bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/47JJACHG">Haaf/Geyken/Wiegand 2015</bibl>) is largely used, which has been extended for the encoding of handwritten texts, <bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/EACNDF7P">(Haaf/Thomas 2018)</bibl>. For a few project-specific concerns, additions and extensions to the tagset were made that are compliant with the TEI guidelines. These extensions relate in particular to project-specific requirements arising from the material, such as the tagging of measurements as well as inserted or appended notes. However, the extensions has been made in a way, that these follow as closely as possible the systematics of the DTABf. Thus, in many cases, instead of adding new elements or attributes, attribute values were added.
urn:cts:humboldtdigital:about.H0021024:1.3.3	p	All names of persons, places and institutions as well as bibliographic references in the source texts (and their metadata) are linked to their respective index entries.

Each entry has its own unique and permanent ID. In addition to the basic data of an entry, a short description is also provided.
urn:cts:humboldtdigital:about.H0021024:1.5.3	p	The entries are also provided with one or more URIs from different authority files, if an entry exists there. This makes it possible to identify persons, places and institutions <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">across projects</hi>, both in ehd itself and when using the APIs and data publication (see also <bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/W4L92XBE">Stadler 2012</bibl> on authority files in editions). For person entries, the GND is primarily used, alternatively or additionally also <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://viaf.org/">VIAF</ref>. For places, on the other hand, URIs from the free geographic database <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.geonames.org">GeoNames</ref> are used, since this achieves a high level of coverage worldwide and entries can be added by the project itself if necessary. Thus, a few localities missing in GeoNames (such as the former locations of the <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/H0000531?l=en">Berlin Observatory</ref>) were added there.
urn:cts:humboldtdigital:about.H0021024:1.5.4	p	Furthermore, the project retrodigitized the index entries of 25 editions (corrspondence, documents, diary excerpts) of Alexander von Humboldt research published between 1973 and 2016 and made them available in the digital index. These index information of the printed editions is part of the series first published by the Akademie-Verlag and finally by De Gruyter <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.degruyter.com/view/serial/BAHF-B"><hi rendition="#i">Beiträge zur Alexander-von-Humboldt-Forschung</hi></ref>, edited by the Alexander-von-Humboldt-Forschungsstelle (1970-2014) of the BBAW.

urn:cts:humboldtdigital:about.H0021024:1.5.6.2	p	On manuscripts of Alexander von Humboldt sometimes so-called "Siglen" (tokens) can be found, i.e. combinations of 1-2 characters (e.g. "Ad") that relate different documents, letters and diary entries to each other. These token were not only transcribed, but also entered into a separate TEI-XML register and linked to it from the text passages. In this way, the relationships can also be traced in the digital edition.

urn:cts:humboldtdigital:about.H0021024:1.5.7.2	p	For the <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/register/pflanzen/index.xql?l=en">plant index</ref>, <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">no</hi> separate entries are created in a TEI-XML index file (as with the other indexes). Instead, the scientific plant names in the edited texts are annotated in the texts using the appropriate TEI encoding, normalized if necessary, and then retrieved automatically. The plant index is thus created completely dynamically. Each distinct plant name has a list of references to the texts and is automatically linked to various taxonomic databases (see below, section <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/H0016212/globalnames">Global indexes for scientific names</ref>).
urn:cts:humboldtdigital:about.H0021024:1.5.7.3	p	Since version 10 (2024), however, the actual dynamic plant register is also automatically created as TEI-XML (including internal and external references). This means that the plant register can also be included in the data publication in the future.

urn:cts:humboldtdigital:about.H0021024:1.6.2	p	The documentation of the data model is done in <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://docs.oasis-open.org/dita/dita/v1.3/dita-v1.3-part3-all-inclusive.html">DITA</ref>, more precisely in the DITA files of <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.ediarum.org/docs/ediarum.BASE.manual/">ediarum.BASE.manual</ref>. This way synergies are used as well as specifications or modifications compared to the data model of ediarum.BASE.edit are documented. DITA (and not ODD) was chosen to enable this combination of ediarum.BASE.manual and the <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/richtlinien/index.html">guidelines of edition humboldt digital</ref>. Furthermore, the internal DITA documentation includes not only the coding guidelines based on the concrete material, but also the <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">operating instructions</hi> for the editors in ediarum.AVHR.edit.

urn:cts:humboldtdigital:about.H0021024:1.7.2	p	While the schema was initially formulated in RelaxNG, it is now maintained as a TEI ODD file <bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/QGGN2BZP">(Viglianti 2019</bibl>) (from which, however, RNG derivatives continue to be created). It is derived using ODD chaining from the ediarum.BASE.schema, which in turn is derived from the DTABf. This makes it possible to maintain and track the respective changes to the next "higher" schema at each level (ediarum, edition humboldt digital etc.). The schema (as TEI-ODD file as well as RNG) are published on <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://github.com/telota/ediarum.AVHR.data-model">GitHub</ref>.

urn:cts:humboldtdigital:about.H0021024:2.2	p	The publication <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">edition humboldt digital</hi> is created in <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum</hi>. The <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.ediarum.org/">digital working environment <hi rendition="#i">ediarum</hi></ref> is a solution developed since 2012 by the <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://www.bbaw.de/telota">DH initiative TELOTA</ref>, that allows scholars to edit transcriptions of manuscripts, comments, and index entries in TEI-compliant XML, add a critical apparatus and notes, and then publish them on the web and as PDFs (<bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/ZFPTSUNP">Dumont/Fechner 2014</bibl>). <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">Ediarum</hi> consists of several software modules. For the input and editing of data, edition humboldt digital uses the module <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum.BASE.edit</hi>, which - as is usual with ediarum - is supplemented by a project-specific module <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum.AVHR.edit</hi> for the edition humboldt digital. The module ediarum.REGISTER.edit is used to create and maintain the index entries. An exception is the bibliography, which is maintained in the literature management software Zotero. For this, <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum.DB</hi> offers an interface for synchronization.
urn:cts:humboldtdigital:about.H0021024:2.3	p	The data is first stored in a Git (<bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/SUJV58N2">Fechner/Klappenbach/Lampert 2025</bibl>) and in a second stage (automated) in an instance of the free XML database <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://www.exist-db.org">existdb</ref>, the module <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum.DB</hi> is used to manage the data. Existdb serves at the same time - together with the web server Jetty - also as basis of the digital edition, which was realized with XQuery, XSLT and XPath and in the meantime in an eXistdb App in accordance with the EXPath packaging specifications, which simplifies Deployment and development. For the search functions, the Lucene-based faceting, available since eXistdb 5.0, is used. In addition, the edition has several specially programmed caches that increase performance, especially for complex queries. For the display of facsimiles, drawings and illustrations the software <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://digilib.sourceforge.net/">digilib</ref>, developed at the MPI for the History of Science, is used.
urn:cts:humboldtdigital:about.H0021024:3	div	
urn:cts:humboldtdigital:about.H0021024:3.1	head	Layout & Web Design
urn:cts:humboldtdigital:about.H0021024:3.2	p	The design of <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">edition humboldt digital</hi> originates from drafts that the author originally developed in 2014 for the project "Schleiermacher in Berlin 1808-1834". Due to the similarity of the edition type and the source genres, the designs could be reused and further developed for the ehd.
urn:cts:humboldtdigital:about.H0021024:3.3	p	The design is based on principles of "flat design", i.e. simplicity, minimalism and a strong focus on typography. Especially the latter is a central point, since this digital edition is about one thing above all: text. Therefore, an Antiqua<hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">(PT Serif</hi>) was chosen as the main typeface, which has a "true" italic cut. It is accompanied by a grotesque <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">(PT Sans</hi>) from the same typeface family, which is mainly used in subnavigations, smaller text and meta information. These <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">classic</hi> typographical conventions, as far as they could be reasonably transferred to the digital medium web, were also taken into account in the further design. For example, a flexible text width oriented to the width of the viewport was dispensed - in favor of a fixed one that corresponds roughly to the typographically recommended line length.
urn:cts:humboldtdigital:about.H0021024:3.4	p	The design approach also does not use a dedicated page header: in order to give the texts as much space as possible, only a low navigation bar was placed at the top, which is clearly visible thanks to the black color. The page header is taken up by the document title or title of the individual page instead of the website title and sponsor etc. logos (which were quite common in 2014). At the same time, this space also provides room for further meta information and sub-navigation (chronological scrolling between letters; sub-section navigation; letters in the index, etc.).
urn:cts:humboldtdigital:about.H0021024:3.5	p	The design has to master two challenges: On the one hand, the abundance of different text types (edited letters, travel journals, documents; research contributions and indexes) and information that need to be accommodated. Here the design of the ehd follows the principle not to show everything immediately, but to fade in certain information only on user interaction. There should always be enough white space to let the eye rest or to group and prioritize the different information in a meaningful way. A second challenge was (and still is) to adapt the design to the changing requirements and the constantly growing amount of material and information. For such a long-running academy project (2015-2032), not every type of information and function was foreseeable at the beginning. Thus, the design has also been adapted again and again - from the introduction of a sub-navigation, to the redesign of the homepage and the introduction of page-based text and facsimile display, to the ever more in-depth and complexly distinguished edited texts. This is sometimes more and sometimes less well done.
urn:cts:humboldtdigital:about.H0021024:3.6	p	The implementation of the design in HTML uses the <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://960.gs">960 Grid System</ref> and relied heavy on CSS. Javascript is only used for special - if necessary replaceable - functions of the interface; the generation of the HTML pages is thus largely server-side to facilitate archiving in the Web Archive or the BBAW Web Archive.

Since Humboldt's correspondence<bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/UGSUKML5">(Schwarz 2018</bibl>) was already considered too extensive to be edited in a complete edition in the 1960s, it has since been published scattered in individual correspondence editions or even essays (especially in the journal <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.hin-online.de">Humboldt im Netz</ref>)<bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/HKNVP8BH">(Schröder 2008</bibl>).

On the other hand, the correspSearch API is queried in the individual view of a letter under "Explore letter network". There, letters from and to Alexander Humboldt from other editions are queried in order to make visible with which other correspondence partners Humboldt still had contact in the respective period. In addition, the letters received and sent by the respective correspondence partner during the corresponding period are displayed - the query is based on the GND or VIAF URI stored in the register.

urn:cts:humboldtdigital:about.H0021024:4.9.2	p	The places and institution locations listed in the register are usually linked to a URI of the free geographic database <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.geonames.org"><hi rendition="#i">GeoNames</hi></ref> provided. This allows the locations to be identified across projects, which greatly simplifies subsequent use of the data. The GeoNames URI is also used to obtain the geographic coordinates, on the basis of which a corresponding map can be displayed with the location and institution entries using the free map service <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.openstreetmap.org/">OpenStreetMap</ref>. This is especially helpful for smaller locations of Alexander von Humboldt's various travels.
urn:cts:humboldtdigital:about.H0021024:4.9.3	p	With version 11 of edition humboldt digital, the geodata-based functions in the place index have been expanded: an <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/register/orte/map.xql?l=en">interactive world map</ref> now provides an overview of all places listed in the place index. In addition, neighboring places that are also listed in the index are displayed within a radius of approx. 30 km of an individual place in its index entry - both on the map and as a list with distance information (example: <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/register/orte/detail.xql?id=H0019176&l=en">Zmeëvka</ref>).

urn:cts:humboldtdigital:about.H0021024:4.10.2	p	Based on the URI noted in an entry of the register of persons from the <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://www.dnb.de/DE/Standardisierung/GND/gnd_node.html"><hi rendition="#i">Common Norm File</hi></ref> (GND), further data can be obtained via the GND web service "Entity Facts". Thus, with the help of the "Entity Facts", on the one hand, portraits are faded in directly from Wikimedia Commons, and on the other hand, information on (family, friendship, etc.) relationships between persons is obtained. These are also automatically evaluated in the ehd on the basis of the GND URIs and then displayed to the users accordingly (see, for example, the <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/H0015944?l=en">entry on Samuel Thomas Soemmerring</ref>).

For this purpose, the texts and entries are not simply exported from the eXistdb, but are retrieved with the help of a XQuery script via the TEI-XML-API 2.0 of <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ehd</hi>, so that the data image matches that of the data accessible via the API. This makes use of the enrichments that take place there (e.g. GNDs; URIs instead of IDs), the harmonizations to the DTABf as well as the division of the register lists into individual TEI-XML files. In the process, the directory structure will also be changed so that the data is organized by type (i.e. letters, diaries, research contributions, register entries, etc.).
