Creating Permissionless Blockchains of Metadata Records Dejah Rubel
Articles No Need to Ask: Creating Permissionless Blockchains of Metadata Records Dejah Rubel ABSTRACT This article will describe how permissionless metadata blockchains could be created to overcome two significant limitations in current cataloging practices: centralization and a lack of traceability. The process would start by creating public and private keys, which could be managed using digital wallet software. After creating a genesis block, nodes would submit either a new record or modifications to a single record for validation. Validation would rely on a Federated Byzantine Agreement consensus algorithm because it offers the most flexibility for institutions to select authoritative peers. Only the top tier nodes would be required to store a copy of the entire blockchain thereby allowing other institutions to decide whether they prefer to use the abridged version or the full version. INTRODUCTION Several libraries and library vendors are investigating how blockchain could improve activities such as scholarly publishing, content dissemination, and copyright enforcement. A few organizations, such as Katalysis, are creating prototypes or alpha versions of blockchain platforms and products.1 Although there has been some discussion about using blockchains for metadata creation and management, only one company appears to be designing such a product. Therefore, this article will describe how permissionless blockchains of metadata records could be created, managed, and stored to overcome current challenges with metadata creation and management. LIMITATIONS OF CURRENT PRACTICES Metadata standards, processes, and systems are changing to meet twenty-first century information needs and expectations. There are two significant limitations, however, to our current metadata creation and modification practices that have not been addressed: centralization and traceability. -

Proceedings of the 6th WSEAS International Conference on Applied Computer Science, Tenerife, Canary Islands, Spain, December 16-18, 2006 356 A 3-tier Application for Topic Map Technology A. PAPASTERGIOU, G. GRAMMATIKOPOULOS*, A. HATZIGAIDAS, G. TRYFON Department of Electronics, (*) Department of Esthetics Alexander Technological Educational Institute of Thessaloniki, EPEAEK II Sindos, 57400, Thessaloniki, Macedonia, GREECE Abstract: In the context of this paper the design and construction of a 3-tier application system for topic map technology is presented in detail. The proposed system employs Enterprise Topic Map Server (ETMS) that manages topic maps (TM) and establishes communication with client applications and persistent database. Yellow Web Services have been customized in order to achieve communication issues and exchange of TM. A client application is addressed to TM developers for editing and visualization of TM. Furthermore, the definition of TM Schema as well as the possibility to process rules and queries are supported. Another key aspect of the present paper is to analyze how different technologies utilized to formulate such a system. Key-words: Topic map, Server, Web services, Client, 3-tier, TM schema, Retrieval 1 Introduction definition of TM Schema as well as the possibility to The Topic Map model describes a mechanism for process rules and queries are also supported.

Mapping Topic Maps to Common Logic
MAPPING TOPIC MAPS TO COMMON LOGIC Tamas´ DEMIAN´ Advisor: Andras´ PATARICZA I. Introduction This work is a case study for the mapping of a particular formal language (Topic Map[1] (TM)) to Common Logic[2] (CL). CL was intended to be a uniform platform ensuring a seamless syntactic and semantic integration of knowledge represented in different formal languages. CL is based on first-order logic (FOL) with a precise model-theoretic semantic. The exact target language is Common Logic Interchange Format (CLIF), the most common dialect of CL. Both CL and TM are ISO standards and their metamodels are included in the Object Definition Metamodel[3] (ODM). ODM was intended to serve as foundation of Model Driven Architecture (MDA) offering formal basis for representation, management, interoperability, and semantics. The paper aims at the evaluation of the use of CL as a fusion platform on the example of TM. II. The Topic Maps TM is a technology for modelling knowledge and connecting this structured knowledge to relevant information sources. A central operation in TMs is merging, aiming at the elimination of redundant TM constructs. TopicMapConstruct is the top-level abstract class in the TM metamodel (Fig. 1). The later detailed ReifiableConstruct, TypeAble and ScopeAble classes are also abstract. The remaining classes are pairwise disjoint. Figure 1: The class hierarchy and the relation and attribute names of the TM metamodel. TopicMap is a set of topics and associations. Topic is a symbol used within a TM to represent exactly one subject, in order to allow statements to be made about that subject. -

Trant, University of Toronto / Archives & Museum Informatics 158 Lee Ave, Toronto, ON Canada M4E 2P3 jtrant [at] archimuse.com Abstract This paper reviews research into social tagging and folksonomy (as reflected in about 180 sources published through December 2007). Methods of researching the contribution of social tagging and folksonomy are described, and outstanding research questions are presented. This is a new area of research, where theoretical perspectives and relevant research methods are only now being defined. This paper provides a framework for the study of folksonomy, tagging and social tagging systems. Three broad approaches are identified, focusing first, on the folksonomy itself (and the role of tags in indexing and retrieval); secondly, on tagging (and the behaviour of users); and thirdly, on the nature of social tagging systems (as socio-technical frameworks). Keywords: Social tagging, folksonomy, tagging, literature review, research review 1. Introduction User-generated keywords – tags – have been suggested as a lightweight way of enhancing descriptions of on-line information resources, and improving their access through broader indexing. “Social Tagging” refers to the practice of publicly labeling or categorizing resources in a shared, on-line environment. -

Geotagging Photos to Share Field Trips with the World During the Past Few
Geotagging photos to share field trips with the world During the past few years, numerous new online tools for collaboration and community building have emerged, providing web-users with a tremendous capability to connect with and share a variety of resources. Coupled with this new technology is the ability to ‘geo-tag’ photos, i.e. give a digital photo a unique spatial location anywhere on the surface of the earth. More precisely geo-tagging is the process of adding geo-spatial identification or ‘metadata’ to various media such as websites, RSS feeds, or images. This data usually consists of latitude and longitude coordinates, though it can also include altitude and place names as well. Therefore adding geo-tags to photographs means adding details as to where as well as when they were taken. Geo-tagging didn’t really used to be an easy thing to do, but now even adding GPS data to Google Earth is fairly straightforward. The basics Creating geo-tagged images is quite straightforward and there are various types of software or websites that will help you ‘tag’ the photos (this is discussed later in the article). In essence, all you need to do is select a photo or group of photos, choose the "Place on map" command (or similar). Most programs will then prompt for an address or postcode. Alternatively a GPS device can be used to store ‘way points’ which represent coordinates of where images were taken. Some of the newest phones (Nokia N96 and i- Phone for instance) have automatic geo-tagging capabilities. These devices automatically add latitude and longitude metadata to the existing EXIF file which is already holds information about the picture such as camera, date, aperture settings etc. -
Semantic Mapping in ROS XAVIER GALLART DEL BURGO
Semantic Mapping in ROS XAVIER GALLART DEL BURGO Master’s Thesis at CVAP/CAS, The Royal Institute of Technology, Stockholm, Sweden Supervisor: Dr. Andrzej Pronobis Examiner: Prof. Danica Kragic August, 2013 Abstract In the last few years robots are becoming more popular in our daily lives. We can see them guiding people in museums, helping surgeons in hospitals and autonomously cleaning houses. With the aim of enabling robots to cooperate with humans and to perform human-like tasks we need to provide them with the capability of understanding human envi- ronments and representing the extracted knowledge in such a way that humans can interpret. Semantic mapping can be defined as the process of building a representation of the environment, incorporating semantic knowledge obtained from sensory information. Semantic properties can be extracted from various sources such as objects, topology of the envi- ronment, size and shape of rooms and room appearance. This thesis proposes an implementation of semantic mapping for mo- bile robots which is integrated in a framework called Robot Operat- ing System (ROS). The system extracts spatial properties like rooms, objects and topological information and combines them with common- sense knowledge into a probabilistic framework which is capable of in- ferring room categories. The system is tested in simulations and in real-world scenarios and the results show how the system explores an unknown environment, creates an accurate map, detects objects, infers room categories and represents the results in a map where each room is labelled according to its functionality. Acknowledgements First and foremost, I would like to express my gratitude to my super- visor, Andrzej Pronobis, for giving me the opportunity to develop my thesis in one of my passions, the robots. -
