CIRSS Seminar: The Basic Representation Model for Digital Preservation and Information Organization
2018-11-02
Information models to handle preservation and information organization have been challenging to apply to digital objects. The Basic Representation Model is designed to be a general framework to account for the multiple and varied levels of representation that occur in the creation, management, and preservation of digital objects. This model was developed in the context of a project focused on the preservation of scientific data, and has the additional potential to support fine-grained information modeling in bibliographic, scientific, and cultural heritage domains. In particular, the model can support clear and explicit connections between information organization, information management, and digital preservation.

E-Research Roundtable: Digital Collection Contexts: Intellectual and Organizational Functions at Scale
2014-04-02
Recent trends in interoperable content and open data have raised a set of issues arising from the representation of context and complex digital objects.  CIRSS, together with collaborators from the Europeana Foundation and the University of Texas at Austin, organized a full-day workshop held at the March 2014 iConference annual meeting to raise the level of discourse and cooperation around these issues and provide iSchools the opportunity to build a community based on strengths and expertise in this important research area.  

Sessions were led by European and North American experts from iSchools and projects developing large-scale digital cultural heritage collections.

CIRSS Seminar: "Representing Identity and Equivalence for Scientific Data," from AGU 2012
2012-11-30
To be presented as part of a session on "Data Stewardship, Citation With Confidence, and Preparing Next Generation of Data Managers," at the upcoming American Geophysical Union (AGU) Fall Meeting, 3-7 December 2012 in San Francisco.

* Paper authors: Karen M Wickett, Simone Sacchi, David Dubin, Allen H Renear

* Abstract:  Matters of equivalence and identity are central to the stewardship of scientific data. In order to properly prepare for and manage the curation, preservation and sharing of digitally-encoded data, data stewards must be able to characterize and assess the relationships holding between data-carrying digital resources. However, identity-related questions about resources and their information content may not be straightforward to answer: for example, what exactly does it mean to say that two files contain the same data, but in different formats? Information content is frequently distinguished from particular representations, but there is no adequately developed shared understanding of what this really means and how the relationship between content and its representations hold.

The Data Concepts group at the Center for Informatics Research in Science and Scholarship (CIRSS), University of Illinois at Urbana Champaign, is developing a logic-based framework of fundamental concepts related to scientific data to support curation and integration. One project goal is to develop precise accounts of information resources carrying the same data. We present two complementary conceptual models for information representation: the Basic Representation Model (BRM) and the Systematic Assertion Model (SAM). We show how these models provide an analytical account of digitally-encoded scientific data and a precise understanding of identity and equivalence.

The Basic Representation Model identifies the core entities and relationships involved in representing information carried by digital objects. In BRM, digital objects are symbol structures that express propositional content, and stand in layered encoding relationships. For example, an RDF description may be serialized as either XML or N3, and those expressions in turn may be encoded as either UTF-8 or UTF-16 sequences. Defining this encoding stack reveals distinctions necessary for a precise account of identity and equivalence relationships.

The Systematic Assertion Model focuses on key provenance events through which propositional content and symbol structures acquire the status of data content and data, respectively. Attention is on events such as a selection of symbols to express propositional content, or an appeal to observational evidence to advance a claim. SAM explicitly identifies data as the primary form of expression the one directly expressing content for a systematic assertion, an assertion where claims are warranted by an observation or a computation event.

Under these models, equivalence relationships may hold between different data expressing the same content, or between different encodings of the same data. Equivalence relationships also hold among different data supporting the same claim and when contrasting claims are based on the same observations. SAM and BRM support a fine-grained characterization of scientific equivalence relationships that can be documented through ordinary data stewardship practices. Read more




E-Research Roundtable: Collection Examples for Europeana Data Model
2012-11-07
We will discussing example collections for modeling collections from the IMLS Digital Collections and Content aggregation in the Europeana Data Model. We are hoping to use these examples to show the benefits integrating collections and collection description into the design of a digital library or aggregation system, by increasing access and by allowing users to understand the context of items and collections.

Our collection narratives are currently under construction, and can be found here: https://apps.lis.illinois.edu/wiki/display/europeana/Examples Read more

CIRSS Seminar: Je t'aime, moi non plus: the tension between technology and documentation practices
2012-02-17
The early-to-mid 2000s economic downturn in the US and Europe forced digital cultural heritage projects to adopt a more pragmatic stance towards metadata creation and to deliver short-term results towards grant providers. It is precisely in this context that the concept of Linked and Open Data (LOD) has gained momentum. Unfortunately, Semantic Web projects sometimes tend to be the victim of a technologically driven vision, where the mean becomes an end in itself. The presentation will put this tension between technologies and documentation practices in a larger context by presenting a hermeneutical framework for the analysis of metadata quality.

CIRSS Seminar: Are Collections Sets?
2011-12-09
The concept of a collection plays key roles in library, museum, and archival practice, and is arguably fundamental to information organization systems in general. Locating collections concepts in a reasonably robust ontology should have a number of practical advantages, including revealing inferencing opportunities on the one hand, and supporting consistency and coherence in system design on the other. However, although practices involving collections have been studied empirically there has been surprisingly little attention given to the formal analysis of the concept itself, or related notions like collection membership. With this paper we hope to convene that discussion, beginning with the question: Are collections sets? We consider in detail the substantial arguments against collections being a kind of set, but recognize that at least one version of that claim, one based on considerations from Guarino and Welty's Ontology evaluation rules, cannot be ruled out. We recognize though that ontology decisions, whether practical or theoretical, ultimately come down to weighing competing considerations and not decisive formal arguments. Any conclusions therefore must await the development of alternative theories in subsequent papers. We invite the information science community to join us in this effort.

E-Research Roundtable: Meditations on the Logical Form of a Metadata
2011-09-07
Open linked data and semantic technologies promise support for information integration and inferencing. But taking advantage of this support often requires that the information currently carried by ordinary "colloquial" metadata records be made explicit and available for computer processing.  Given the fairly simple structured nature of metadata records this looks easy to do. Turns out though that it is not at all easy to do. A number of very fundamental puzzles arise, some of them related to identifier elements, others are issues with knowledge representation in general.  Although related problems have been studied here at GSLIS for some time, the current systematic development is largely new -- its first exposure was just a few weeks ago as a "Late Breaking" report at "Baliage: The Markup Conference" (Montreal). It is also very much a work in progress (with suspected flaws) and so this is an invitation to participate in evolving this account of what metadata records really are, and how they do what they do.

CIRSS Seminar: Making Digital Curation a Systematic Instional Function
2011-02-04
Over the past decade, a rich body of research and practice has emerged under the rubrics of electronic records, digital preservation, and digital curation but few traditional archives have implemented systematic methods to capture, preserve, and provide access to the complete range of documentation that end users need to understand and interpret past human activity.

This talk describes the Practical E-Records Method, which attempts to address this problem by providing easy-to-implement software reviews, guidance/policy templates, and program recommendations that blend digital curation research findings with traditional archival processes and workflows. Using the method discussed in this paper, archives and manuscript repositories can use existing resources to incrementally develop digital curation skills, building a collaborative, expanding program in the process. Archival programs that make digital curation a systematic institutional function will systematically gather, preserve, and provide access to genres of documentation that are contextually-rich and highly susceptible to loss, complementing efforts undertaken by librarians, information scientists, and external service providers. Over the next year, the suggested techniques will be tested and refined at the University of Illinois Archives and possibly elsewhere.Read more




CIRSS Seminar: Rule Categories for Collection/Item Metada Relationships
2011-01-28
 Collections of artifacts, images, texts, and other cultural objects are not arbitrary aggregations, but are designed to support specific research and scholarly activities. Collection-level metadata directly supports this objective, providing critical contextual information. However, exploiting this information, especially in a semantic web environment of linked data, requires a precise formalization of the rules that characterize collection/item metadata relationships. Toward this end we are developing a logic-based framework of relationship rule categories for collection/item metadata. This framework will support metadata specification developers, metadata catalogers, and system designers. This presentation summarizes the results of a three year effort, part of the IMLS Digital Collections and Content project.

CIRSS Seminar: The Modifiability Puzzle
2010-09-24
We summarize presentations given at ASIS&T 2008 (Allen Renear, Karen Wickett, Dave Dubin) and Balisage 2009 and 2010 (Renear and Wickett) that analyze problems in our commonsense understanding of digital objects. The discussion of these problems began some years ago in the GSLIS Electronic Publishing Research Group and has more recently continued at times in the Conceptual Foundations Group. Related topics are now being actively pursued within the Data Concepts group (Dubin, Renear, Wickett, and Simone Sacchi) of the NSF funded Data Conservancy.

Abstract: The digital world seems to be a place of constant change. Documents are edited, databases updated, files modified, datasets reformatted, and so on. But apparently we are deluded. Standard theories of what digital objects are entail that those objects are immutable and cannot undergo any genuine modification at all. It gets worse. Arguments against modifiability do not apply only to digital objects and do not depend upon specialized definitions -- in a few simple steps ordinary beliefs lead to paradoxes about many things.

Embedded inconsistencies in our commonsense beliefs have long entertained philosophers, but our problem here is more than an idle Milesian amusement. While for the most part human beings manage quite well with inconsistent conceptual schemes, the emerging world of linked data and semantic technologies depends on precise definitions and straightforward logical reasoning, and carries out automatic inferencing, based on those definitions, often with few opportunities for human intervention and correction.

How can we reconcile our commonsense concepts of documents, databases, datasets, and the like with the unforgiving demands of semantic technologies? We believe this is a profound and urgent open question in information science and that the success of semantic technologies and linked data depends on its resolution. On Friday, we will not defend a specific answer but rather try to make the problem clear, and show that none of the known resolutions are without difficulties. We present you with the puzzle -- you tell us how to solve it.
