VALEP:About

VALEP was was launched in May 2021, e.g., on Daily Nous, Leiter Report and the IVC website. The development team includes Christian Damböck (design), Catherine Schlienger and Maximilian Damböck (programming), Helena Müller (UX Design), Brigitta Arden, Lucas Baccarat, Philipp Leon Bauer, Roman Jordan, Lois M. Rendl, and Miguel De la Riva (data processing).

VALEP and Phaidra

All VALEP data are mirrored in the University of Vienna's digital repository Phaidra. The staff and consultants of Phaidra support the development of VALEP, including aspects of archival science (Susanne Blumesberger), database design and the technical integration of Phaidra (Raman Ganguly), copyright issues (Seyavash Amini Khanimani), and all details of the metadata design of VALEP (Rastislav Hudak).

Cooperation Partners of VALEP

We are looking for cooperation partners among international archives that hold material on the history of Logical Empiricism. If you are interested in cooperating with VALEP as an institution, or if you are simply using VALEP for your own research and are interested in depositing your collected material, please contact Christian Damböck.

Archives of Scientific Philosophy (ASP), University of Pittsburgh Library System

The Archives of Scientific Philosophy of University of Pittsburgh Library System has been sharing their electronic resources with VALEP. This includes scans produced by the ASP of the Papers of Rudolf Carnap, Carl Gustav Hempel, Richard C. Jeffrey, Hans Reichenbach, Frank Plumpton Ramsey, and Rose Rand. The material comprises about 30,000 scans and is already available in VALEP. We would like to thank Ed Galloway for his most generous support and Clinton T. Graham for transferring the files.

Brenner Archiv, University of Innsbruck

The Brenner Archiv which houses the Nachlass of Wolfgang Stegmüller made available parts of the correspondence of Wolfgang Stegmüller and his dissertation and habilitation thesis in VALEP. This comprises more than 7,000 scans and correspondences with philosophers such as Hans Albert, Max Black, Rudolf Carnap, Herbert Feigl, Carl-Gustav Hempel, Thomas Kuhn, Paul Lorenzen, and Joseph Sneed. Thanks go to Michael Schorner for preparing the scans and to Ulrike Tanzer for granting the permission to put the material online.

Moritz Schlick Forschungsstelle, University of Rostock

In 2022 VALEP made a cooperation agreement with the Moritz Schlick Forschungsstelle in the form of a formal agreeement between the Univerities of Rostock and Vienna. Part of the cooperation will be that the Moritz Schlick Forschungsstelle step-by-step uploads scans of the entire Moritz Schlick Nachlass which comprises more than 50,000 pages. These scans of the Nachlass which is located at the Noord-Hollands Archief in Haarlem were prepared by the Moritz Schlick Forschungsstelle as part of their Moritz Schlick Edition Project. The Moritz Schlick Forschungsstelle will made available the scans in VALEP and it also will process the files into documents. Future plans also include an electronic edition of the published and unpublished works of Moritz Schlick. Thanks go to Matthias Wunsch and Martin Lemke for their generous support and fruitful cooperation.

The Wittgenstein Archives at the University of Bergen (WAB)

The WAB agreed to share material from its Bergen Nachlass Edition (BNE) of the estate of Ludwig Wittgenstein which is currently available at Wittgenstein Source and make it available in VALEP. This will include scans of the manuscripts and, in a future stage of the cooperation, also the XML transcriptions of the works from the Wittgenstein Nachlass. Thanks go to Alois Pichler for his generous support and to the Wren Library at Trinity College Cambridge for granting the permission to upload the material in VALEP.

The Technical Implementation of VALEP

The technical implementation of VALEP

VALEP uses the following system architecture

• A backend that is implemented in Java - Spring-Boot and uses a PostgreSQL Database
• Additional services that include
  • an EDTF-Service (NodeJS) for parsing data entries
  • (in future implementations) services for Data Import (LaTeX, external SQL databases) inside of the Java backend
  • (in future implementations) services for transfer from LaTeX to TEI-XML and HTML (written in Python)
• Local users correspond with the backend via an Apache Webserver (Angular) and a Keycloadk - OAuth2 User Access Management

VALEP uses the following strategies for data security and long-term availability of data

• Daily data backup with the standard tools provided by the University of Vienna
• Regular data backup to non-local computers
• Persistent links via DOI
• Use of standard formats such as jpg, tiff, pdf, mp3, mp4 for electronic files and LaTeX, HTML, TEI-XML for electronic editions
• Mirroring of all data at Phaidra
• (in future implementations) integration of data on persons, institutions, locations, etc. in existing online databases such as Wikidata

The Scope and Mission of VALEP

VALEP is an archive management and edition tool that is intended as a platform for the history of Logical Empiricism and related currents. (Presentation from September 2022)

VALEP functionalities:

• (left/red part of the window) representation of the hierarchical structure of an archives, including archives, collections, digital reproductions, shelves, boxes, folders, files

• (middle/green part of the window) transformation of archival material into objects that belong to a certain document category, document type and that are uniquely identified by metadata that include title, description, author, date

• (upper right/yellow part of the window) archive nodes and documents are characterized by metadata that can be accessed in the upper right section of the screen

• (lower right/blue part of the window) Files, documents, and editions can be viewed in an integrated document viewer (already available) and the objects can be downloaded and printed (to be implemented in 2021)

VALEP records titles, descriptions and the like in the text format unicode. But some metadata categories, including date, location, language, persons, and institutions, are stored in a relational database and/or using special formats and parsing tools, e.g., EDTF for dates, and an internal tool for the mereological structure of locations. See the metadata page for the details. In future implementations (presumably comming in 2024/25) VALEP will integrate its data on persons, institutions, locations in external resources such as Wikidata.

The Place of VALEP within the Digital Humanities

VALEP's goals is the collection of large amounts of data. The history of Logical Empiricism, together with related currents, such as Neokantianism, French Positivism, British Empiricism, and American Pragmatism, comprises dozens of major and probably thousands of minor individuals, including academic and private scholars. Their papers can be found in public institutions and private collections, as well as additional material collected by academic and private institutions. There are thousands of manuscripts, publications, and probably millions of letters that might add significant research value in one way or another in our studies of Logical Empiricism. VALEP allows us to store, preserve, evaluate, and (in future implementations) also edit all these sources, as soon as they become available in digital form. One can organize, search and filter them in VALEP according to ones needs and interests.

VALEP's Innovative Approach

Existing tools for the management of archival sources include (1) tools that academic archives, such as the Archives of Scientific Philosophy provide; (2) open tools such as PhilArchive, where anybody can upload electronic documents; (3) tools tailored to the presentation of material of a specific origin, such as the papers of Ludwig Wittgenstein. All these tools have in common that they are more or less document oriented. They do not mirror the physical structure of an archive, but rather store documents according to a particular unit of metadata. This approach could be fruitful, if the documents are processed thoroughly and the associated metadata is clear, transparent and sufficiently complex.

However, most of the existing tools include only rudimentary metadata, and, in the case of public archives, single documents are not processed as a logical unit (e.g. letter from Otto Neurath to Rudolf Carnap from December 26, 1934), but rather, the archives provides constructed units, e.g., folders that contain several letters from Carnap to Neurath from the years 1923 to 1929. Sometimes, they might even include material unrelated to the main topic of the unit. In such cases, offering effective and meaningful metadata may not be possible at all, simply because the document units are too inconsistent.

Advantages of an Archive Oriented Presentation

When a digital archive only provides rudimentary metadata and rather ambiguous documents, it might be helpful to present the digital material in a way that reflects the physical structure and arrangement of the archive. Archives typically structure their material into collections and subcollections (or series and subseries), shelves, boxes, folders, etc. This detailed structure already represents a certain order, e.g., distinguishing between manuscripts and correspondence, providing a chronological arrangement, and/or selecting topics or correspondence partners. Despite remaining inconsistencies, archive users are usually able to work with a mnemotechnical approach, often supported by the archival finding aids. Representing the digital material according to the physical arrangement of the analog archive, might increase the transparency and usability of digital archival sources.

The Logarithmic Scale of Archival Work

Structuring a digital archive according to its physical organization in the analog world also yields a major pragmatic benefit. If digitized copies are stored in folders that mirror the structure of the analog archive, then you could upload the entire material, basically, with a single mouse click. The archival work involved is close to zero. On the other hand, if this archive is really large as, for example, the Schlick Papers in Haarlem, which comprises some 50,000 pages, or the Carnap Papers at the ASP, which consists of close to 100,000 pages, then you can expect to process tens of thousands of documents. If an archivist, say, is processing 20 documents per hour, this eventually will amount to several years of full time work. As you can see, we are here comparing two extremes on the scale of gains divided by working time. Most archival resources won't be processed at such a micro level, for mere lack of time and funding. However, these sources might still be available, at the level of representation of the physical structure of the repository.

The Importance of Metadata

Metadata can be needlessly complex and confusing. Therefore, a careful selection is important. For example, a document should only be associated with relevant metadata categories. Only a letter, for example, has a recipient or a place of posting, whereas a manuscript, unlike a published book or article, may not offer any publication date. So, one important aspect of making metadata adequate is by restricting certain document categories to only category-relevant metadata.

Metadata should have a consistent format. Especially crucial metadata such as date and location. Dates should be able to cover not only (several) single days but also entire months or years, and date ranges, e.g. from December 24, 1924, until October 1930. Such an approach will cover also cases where the date of a document is not clear or where a document was produced over a longer period and/or at different days or years. Locations, on the other hand, should become embedded into the mereological structure of geography. The fact that Vienna, for example, belongs to Austria and Europe but also to the Habsburg Empire and the German-speaking world, is a complex relationship structure to represent, but necessary in order to find all Viennese locations when filtering documents for Vienna, Austria, Europe, the Habsburg Empire, or the German-speaking world. Finally, in other cases, such as with individuals, institutions, languages, we can design an application with a precise search and filter function when we establish relational features and store them in predefined lists or tables. References to these predefined resources, however, should be optional, in order to keep the database structure as flexible as possible.

Archival Documents from Different Repositories: The Merging of Formats and Versions

An important aspect of merging several archival sources is that documents tend to be located not only in one folder/box held by one collection. Rather, we often find the following scenarios:

• An original document is held in archive X, whereas copies are located in other archives, e.g., carbon copies of a letter kept by the sender (which might contain relevant information that the original letter does not provide)
• Written duplicates of a document might exist, transcriptions and translations, as well as commentaries that are located at different archival repositories.
• A document might consist of several parts or chapters that, in turn, might be scattered among different archives (some of them might be the original, some might be copies, written duplicates, transcriptions, etc.)

A Note on Copyright

The international copyright legislation generally stipulates open access to metadata, whereas reproductions may be published online only if (a) the copyright was granted to the publishers by the copyright holder(s), or (b) the legal situation allows for publication without explicit transfer of copyright. There are two typical scenarios for (b): (b-1) publication of a document is possible if the death dates of all authors involved is more than 70 years ago, which turns the material into public domain; (b-2) publication is possible if the publishers can prove that the copyright holders could not be identified, despite all reasonable efforts to do so.

Copyright Protection vs. Research Access: The Flexible VALEP Approach

A logarithmic scale is emerging here. Prominent individuals, such as Carnap, Reichenbach, or Quine, could usually obtain copyright for their works easily. However, among their papers is also a wealth of material authored by others - letters TO Carnap, Quine, Reichenbach - or material that touches on privacy rights of others - e.g. Carnap discussing a specific person in a letter. Resolving all copyright issues unfolding from a Nachlass can turn into a tedious and unmanageable task. Therefore, it would be advantageous if a database could deal with these issues in a flexible way. Some material might be either removed from public access in its entirety - metadata plus reproductions - or public access will be granted (because metadata are unproblematic), but with restricted access to reproductions. Moreover, access can be restricted to the internal/non-public realm of the database, allowing access only to authorized staff.

Improving Research Tools Across Archival Repositories

To sum up, the following features would improve existing archival tools:

• representation of the physical structure of an archive (in order to support the mnemotechnical skills of researchers and make existing finding aids more useful)
• concentrating on areas with high gains and low costs first, continuing with the rest -- high gains and high costs -- only when feasible through available funding
• providing a flexible approach towards metadata categories, matching them with the pertinent document categories
• ensuring that critical metadata categories, such as date and location, use a flexible, consistent and transparent format, together with suitable parsing tools (to avoid inconsistent entries)
• implementing additional critical metadata via predefined lists and tables in a relational database setting, while keeping data fields optional whenever possible
• providing efficient tools that enable the processing of related documents held at different institutions, which can exist in a variety of formats, versions, expressions, such as carbon copies, transcriptions, or annotated duplicates
• allowing for parts of the published material to remain restricted - access to the metadata but not to the reproductions - or even restricting both metadata and reproductions, as long as copyright issues remain unsolved

VALEP as an Innovative Tool

Indeed, VALEP does provide all aforementioned features. From the start, the database design was centered around the idea of reflecting both the physical structure of an archive as well as its content. From this initial focus, all additional innovative features have naturally evolved. One example are the concepts of 'versions' and 'chapters'. They manage to intermediate between the realms of (general) documents and archives. The development of these concepts were in part inspired through feedback from archivists and the designer's own archival experience.

Who Can Use VALEP?

VALEP is available to the general public, and it's free of charge in all its applications. Typical users of VALEP might include:

• public and private institutions that hold material on the history of Logical Empiricism, using VALEP as a tool to publicize their sources and join them with other relevant material
• private researchers wanting to utilize VALEP not only to distribute and merge their sources but also to preserve them for the future
• researchers from all over the world who obtained digitized archival copies and are willing to share them with the research community, and/or want to process and organize their sources

If you are interested in using VALEP as an institution, private individual, or researcher, please contact Christian Damböck.

Future plans include:

• traffic protocols, display of internal data and statistics for each VALEP element
• integration of digital representations of texts and comments using LaTeX, XML, and a Git hub
• WikiData integration for persons, institutions, locations, and other metadata items
• more powerful filter tools that also allow to search the archive tree
• option to selectively restore deleted VALEP objects
• option of flagging objects in VALEP, together with advanced filter tools
• loading bundles of documents into the file viewer
• downloading JPGs within the file viewer as PDFs
• option to download the nested content of any node of the archive tree to a local computer
• XML and LaTeX download
• displaying the number of files belonging to each node of the archive tree
