The new MHDBDB is currently in the development beta phase. Some functions, especially complex searches, are therefore not yet fully supported. In such cases, the old MHDBDB will still be available during the transition period. 

Nevertheless, there are a large number of new features, advantages, and improvements:

- Almost all works can now be read in full-text mode, which allows for better contextualization of search commands. The MHDBDB thus better fulfills its claim to be a “text archive before 1600.” 

- Almost all works (with a few exceptions of newer editions that are not subject to the editio princeps scheme and for which it is therefore not legally possible) and all in-house annotations to works are available for download.

- Linked Open Data/Semantic Web: All MHDBDB tokens, annotations, metadata, and the like have their own IDs and are linked to the Semantic Web. 

- Visual search/term system: Regular users will remember the cumbersome number codes of the old MHDBDB. For example, the search string “minne & 21111307” returned results for the word minne with the semantics “drink” (i.e., the minne drink). These codes are a thing of the past, replaced by the visual search mask. 

- Simple search option by part of speech (POS): Where parts of speech could previously only be found using complicated search strings (“sin & <NOM>”), there are now easy-to-use checkboxes. 

* Word families/word formation: Compounds and derivatives of words are now clearly displayed in the “lemmas” section. 

- Lemmas with similar semantic fields: Based on the system “Customers who were interested in this book also bought that book,” we have added so-called association relations with similar semantic fields to all lemmas. For example, ‘mûs’ is tagged with “small mammals” and “mammals.” The same semantic combination is also found in “ratz,” which is now displayed here in the mûs lemma and is intended to encourage further browsing.

- The metadata of the corpus has been clearly organized. Underlying editions are transparently identified.

- Linked Open Data (also) in the area of bibliographic metadata: As an additional service, author and work data have been linked to standard data from Wikidata, GND, and Handschriftencensus. The links can be found under “Works.”

- Biographical data of authors: The “Advanced Filters” include a time slider for the biographical data of authors, which allows the search to be specified in more detail. 

- New MHDBDB naming system: Proper names have been removed from the previous semantic “concept system” and transferred to a separate onomasticon (SKOS). 

- New MHDBDB concept system: The eponymous concept system, which is based on the system developed by Rudolf Hallig and Walther von Wartburg (1952), has been implemented in SKOS in the form of a controlled vocabulary and now includes polyhierarchies (hierarchical structures in which a class can have more than one superordinate class), various labels (synonyms), languages, and additional notes. 

- New MHDBDB text series typology: The outdated 36 “text types” have been abandoned. Instead, there is now a complex categorization system based on genres or text series with over 600 entries (SKOS). These serve as filters on the one hand, but also as a classification system in the metadata on the other.

- MHDBDB DH tools for download: The MHDBDB team has developed a number of software tools that are available for reuse, e.g., a tagger model for Spacy v3, an mhd. stopword list, an XQuery module API for Transkribus PageXML, etc. 

- MHDBDB Zotero Library: The MHDBDB has been around since the 1970s. Its in-house publications are correspondingly extensive and diverse, as are those that write about the MHDBDB or use it for research. We have attempted to collect all these publications and will make our own publications freely available as far as possible in the coming months, which could be particularly beneficial for the scientific history of DH. See www.zotero.org/groups/5043625/mittelhochdeutsche_begriffsdatenbank/library.
