Mash-Up Personal Learning Environments (MUPPLE)Hannes Ebner
This document discusses mash-up personal learning environments and tools for creating mash-ups. It provides an overview of services and tools for mashing up data, including Yahoo! Pipes, Dapper, openkapow, Ubiquity, and Chickenfoot. The document outlines tasks for workshop participants to visualize what their personal learning environment could look like and how they would realize it using various mash-up tools.
This document provides an overview of changes to New Jersey's statewide assessments starting in the 2007-2008 school year for grades 5-8. Key changes include adding more reading passages and writing prompts to the language arts literacy section, testing mathematics over two days for grades 5-7, and introducing a new short constructed response item type to the mathematics section. It outlines the testing schedule, new testing features for language arts literacy and mathematics, and provides examples of writing prompts and reading passages.
Collaborative Construction of ArtifactsHannes Ebner
This document discusses collaborative construction of artifacts using an information directory called Collaborilla. It describes how artifacts like context maps can be collaboratively authored by allowing multiple contributors to add metadata and optional contributions. Collaborilla manages the metadata and dependencies between contributions, allowing perspectives on an artifact to include standard and optional additions. This enables simultaneous yet integrated work by multiple users without versioning conflicts. Future work may explore encouraging broader participation and transparency of ownership.
Resource and Metadata Management with a Linked Data perspectiveHannes Ebner
This document summarizes a presentation on resource and metadata management from a linked data perspective. It discusses projects like Organic.Edunet that deal with heterogeneous metadata from multiple standards and stakeholders. It also outlines the conceptual overview of the EntryStore system for managing linked data, including named graphs, REST API, ACLs, harvesting, querying, and SPARQL. Some lessons learned are around ontologies being difficult for annotators to grasp, the need for clear licensing of data versus metadata, and the complexity involved in practical implementation at large scale.
This document discusses loose and ad-hoc collaboration. It focuses on collaborative construction of artifacts in a way that allows the same approach to be applied in different contexts to create contextualized artifacts through collaboration without strict guidelines.

The document provides an introduction to Dublin Core metadata, including:
1) Dublin Core is a set of metadata standards including 15 simple elements and over 50 qualified elements for describing resources.
2) Dublin Core metadata can be used to improve resource discovery and is recommended for metadata harvesting and the semantic web.
3) Custom mappings can be made from other metadata standards like LOM to the Dublin Core Abstract Model to make metadata interoperable.
Organic.Edunet is a multilingual repository for learning resources about organic agriculture and agroecology in Europe. It uses Semantic Web technologies to provide a conceptual overview with abstraction of data storage and metadata annotation. Resources can be harvested and queried using standards like OAI-PMH and SPARQL. An ontology is used for semantic search and classification. After six months of intensive population, the repository contains over 6,000 harvested and 1,000 imported resources, with a target of more than 10,000. It provides interoperability through open standards and aims to support linked data.
Learning Object Annotation in Agricultural Learning RepositoriesHannes Ebner

This presentation provides an overview over the content repository architecture of the Organic.Edunet eContentplus project.
A Mashup-friendly Resource and Metadata Management FrameworkHannes Ebner
The document discusses a framework for managing resources and metadata to support mashups and personal learning environments (PLEs). It proposes that mashups combine multiple data sources through public APIs and standard protocols like HTTP, while PLEs are personalized mashups. The framework aims to address limitations of existing standards for resource management by defining what a resource is and how to manage metadata. It also describes the framework's design, technologies, interfaces, use cases, and improvements over current approaches.
