This paper argues that Directory support of PGP infrastructure can help overcome some of the drawbacks of this PKI. It also states some general requirements for a storage model for PGP keys. |
| Zur Neustrukturierung des Deutschen Teilbaums im X.500/LDAP Directory | Peter Gietz | DS-Info 2, Hg. DFN, Directory | 1999-10-29 | article | X.500, LDAP, Directory, German Subtree | | ABSTRACT: Aufgrund der kontinuierlichen Zunahme von Organisationseinträgen im deutschen Teilbaum des X.500 wird dessen Neustrukturierung zwingend notwendig. In diesem Text wird angestrebt, durch Einführung von zusätzlichen Gliederungsebenen eine neue Struktur zu definieren, die den antizipierten Bedürfnissen der Zukunft gerecht werden kann. Nach einer Beschreibung des Ist-Zustands und seiner Probleme und nach Referierung einiger bisheriger Arbeiten zum Thema wird eine Strukturierung nach geografischen Gesichtspunkten definiert. Schließlich wird das Konzept der "Sichtweisen", also Aliase, die gleichartige Organisationseinträge gruppieren, beschrieben und ihre Anwendung im deutschen Teilbaum definiert. |

Marco Thorbrügge, Hamburg | 2004-02-03 | article | LDAP, Authentication | | ABSTRACT: LDAP wird zunehmend für Authentifizierungsprozesse verwendet und hat sich diesbezüglich zu einem Standard-Mechanismus entwickelt. Viele Anwendungen besitzen eine integrierte LDAP-Schnittstelle für die Authentifizierung von Benutzern und auch Login-Prozesse können über LDAP abgewickelt werden. Dies hat den Vorteil, dass ein Benutzer sich nur ein einziges Passwort merken und der Administrator nur eine einzige Benutzerverwaltung administrieren muss. Allerdings wird die Kompromittierung des zentralen Passworts auch zu einem erhöhten Sicherheitsrisiko, weshalb die Sicherung der in LDAP gespeicherten Passwörter eine wesentliche Voraussetzung für LDAP-basierte zentrale Authentifizierungssysteme ist. Der Beitrag führt in das Thema ein, beleuchtet die diesbezüglichen Bedrohungsszenarien, sowie die verschiedenen möglichen Abwehrmaßnahmen. |

| Citation segmentation from sparse & noisy data: A joint inference approach with Markov logic networks | Dustin Heckmann, Anette Frank, Matthias Arnold, Peter Gietz, Christian Roth | Literary and Linguistic Computing, Volume 31, Issue 2, 1 June 2016, Pages 333–356, Hg. Digital Scholarship in the Humanities | 2014-12-08 | article | | | This article presents an approach to citation segmentation that addresses special challenges as typically found in Digital Humanities applications. We perform citation segmentation from Optical Character Recognition (OCR) input obtained from volumes of a printed bibliography, the Turkology Annual. This showcase application features serious difficulties for state-of-the-art techniques in citation segmentation: multilingual citation entries, lack of data redundancy, inconsistencies, and noise from OCR input. Our approach is based on Markov logic networks (MLN) (Richardson and Domingos, Markov logic networks. Machine Learning, 62(1): 107–36, 2006), a framework of statistical relational learning that combines first-order logic with probabilistic modeling. Formalization in first-order logic offers high expressivity and flexibility, and makes it possible to tailor segmentation to specific conventions of a given bibliography. We show that in face of the specific difficulties found with seg... |
| TextGrid and eHumanities | Peter Gietz, Andreas Aschenbrenner, Stefan Büdenbender, Fotis Jannidis, Marc Wilhelm Küster, Christoph Ludwig, Wolfgang Pempe, Thorsten Vitt, Werner Wegstein, Andrea Zielinski | Proceedings of the Second IEEE International Conference on e-Science and Grid Computing E-SCIENCE ´06. IEEE Computer Society 2006. Amsterdam 2006 | 2007-01 | article | TextGrid | | TextGrid is a new Grid project in the framework of the German D-Grid initiative, with the aim to deploy Grid technologies for humanities scholars working on historical (German) texts. Its two roots, humanities computing and eScience (Grid computing used by research together with modern communication technologies), are the basis for TextGrid to provide pioneer work in eHumanities. After summarizing Humanities Computing and modern network technologies, community expectations in the fields of philological edition and other application areas are set forth, from which functional requirements such as modularity, distribution, etc. are distilled. The first version of the TextGrid architecture was designed in accordance with these requirements, and focuses on openness by standard conformance and encapsulation. It provides storage Grid services via a pure Web Services interface to dedicated Web Services tools for different aspects of text processing, analysis and retrieval. This platform aims to provide easily usable tools for scholars, but also specifies interfaces for external program developers to add functionality. |
| A concept for attribute-based authorization on D-Grid resources | Ralf Groeper, Christian Grimm, Siegfried Makedanz, Hans Pfeiffenberger, Wolfgang Ziegler, Peter Gietz, Michael Schiffers | Future Generation Computer Systems, Volume 25, Issue 3, March 2009, Pages 275-280 | 2009-03 | article | Attribute-based authorisation, VO-management, VOMS/VOMRS, GridShib, Shibboleth | | In Germany’s D-Grid project numerous Grid communities are working together to provide a common overarching Grid infrastructure. The major aims of D-Grid are the integration of existing Grid deployments and their interoperability. The challenge lies in the heterogeneity of the current implementations: three Grid middleware stacks and different Virtual Organization management approaches have to be embraced to achieve the intended goals. In this article we focus on the implementation of an attribute-based authorization infrastructure that not only leverages the well-known VO attributes but also campus attributes managed by a Shibboleth federation. |

| GeoTwain: Geospatial analysis and visualization for researchers of transculturality | Matthias Arnold, Konrad Berner, Peter Gietz, Kilian Schultes, Roland Wenzlhuemer | E-Science Workshops, 2009 5th IEEE International Conference, Oxford, UK, Hg. IEEE | 2009-12-11 | article | | | In our research cluster on transculturality many projects deal with georeferenced data. This paper offers an introduction to the new project GeoTwain that works on visualisation techniques for such data. Based on an analysis of the global telegraph network as an example of transcultural research using geo-referenced data, the paper derives user requirements by combining experiences gained from previous projects and specifies a set of solutions. It is the aim of GeoTwain to provide easy visualization of 4-D-information based on Google Earth and to grasp spatial relationships embedded in historical evidence to analyse, recombine and disaggregate geo-referenced historical data without having to use more specialized and highly complex GIS Tools. Envisioned visualization with GeoTwain allows for fast and efficient assessment of georeferencing's analytical potential in any given case; it also allows the user to carefully weigh further investments in data enrichment in relation to expected findings. Both the development and application of GeoTwain are embedded in the broader research environment infrastructure called Heidelberg Research Architecture (HRA). |
| TEI documents in the grid | Andrea Zielinski, Wolfgang Pempe, Peter Gietz, Martin Haase, Stefan Funk, Christian Simon | Literary and Linguistic Computing, Volume 24, Issue 3, 1 September 2009, Pages 267–279, Hg. Digital Scholarship in the Humanities | 2009-05-14 | article | | | This article describes the life cycle of a TEI Document within TextGrid, an eHumanities platform for scholarly text processing, in which structured search is based on the TEI framework and metadata with restricted values. A workbench is provided that offers tools for handling TEI documents, TextGridLab, making it easier to annotate, process, search, and persistently store new digitized texts. The digitization and annotation of the Campe dictionary1 serves as a first test bed. The overall framework of TextGrid is very generic and can handle different types of text (literary editions, linguistic corpora, lexica) as well as heterogeneous data formats (plain text, XML/TEI, images). In fact, the TextGrid repository, TextGridRep, is designed as a digital virtual library over federated archives, where humanities projects are invited to participate. Sharing of data is enabled by means of a grid-based architecture. Specifically the middleware includes most of the treatment of authorization, search, and file management. TextGrid is entirely based on open source software including Eclipse2 and Globus Toolkit. |
| Access to the DARIAH Bit Preservation Service for Humanities Research Data | Peter Gietz, Danah Tonne, Jedrzej Rybicki, S.E. Funk | Queen’s University Belfast, Hg. © 2012 IEEE | 2013-02 | article | | ![]() | Sustainable management of large amounts of research data is gaining in importance for research projects all over the world. The European project DARIAH aims to address this topic for the arts and humanities community. The DARIAH Bit Preservation, as a part of an archiving system for the arts and humanities, allows for a high performance, sustainable, and distributed storage of research data as basis of virtual research environments. A great challenge in designing such a service is to provide a standardized, consistent yet easy-to-use API for accessing the data that remains stable even if backend technology changes over time. As a solution, this paper presents the RESTful API of the DARIAH Bit Preservation which includes an administrative extension, and which is secured by an Authentication and Authorization Infrastructure (AAI) based on SAML. An exemplary implementation illustrates that the API offers distributed access by usage of the HTTP protocol and is able to handle a high number of files. Data transfer rates of up to 45 MB/s were achieved for uploading large files in the local network. |

| Federated Identity Management for Research | Thomas Barton, Peter Gietz, David Kelsey, Scott Koranda, Hannah Short and Uros Stevanovic | EPJ Web of Conferences | 2019-09-17 | article | | | Federated identity management (FIM) is an arrangement that can be made among multiple organisations that lets subscribers use the same identification data to obtain access to the secured resources of all organisations in the group. In many research communities there is an increasing interest in a common approach to FIM as there is obviously a large potential for synergies. FIM4R [1] provides a forum for communities to share challenges and ideas, and to shape the future of FIM for our researchers. Current participation covers high energy physics, life sciences and humanities, to mention but a few. In 2012 FIM4R converged on a common vision for FIM, enumerated a set of requirements and proposed a number of recommendationsfor ensuring a roadmap for the uptake of FIM [2]. In summer 2018, FIM4R published an updated version of this paper [3]. The High Energy Physics (HEP) Community has been heavily involved in creating both the original white paper and the new version, which documented the progress made in FIM for Research, in addition to the current challenges. This paper presents the conclusions of this second FIM4R white paper and a summary of the identified requirements and recommendations. We focus particularly on the direction being taken by the Worldwide LHC Computing Grid (WLCG), through the WLCG Authorisation Working Group, and the requirements gathered from the HEP Community. |

profile for implementing mappings between the SAML 2.03 and OpenID
Connect4 (OIDC) protocols, in the context of use cases in Research and
Education.
It describes how to map identifiers and commonly used attributes into scopes
and claims for use with the OIDC protocol, and vice versa.
The document contains three main sections:
- A discussion on how to map between identifiers used in SAML and
OIDC;
- A recommendation for a basic attribute and claims mapping profile,
which should be useable with unmodified OIDC clients which implement
the standard claims5 of the OIDC core6 standard; and,
- A recommendation for an advanced mapping profile, which will
leverage the full set of attributes made available by the eduPerson- and
SCHAC schema but requires handling additional, (currently) non-
standard claims and scopes. |
