ApacheCon US 09 starts today in Oakland. A couple of Day's engineers will give talks, not just about the usual suspects Sling and Jackrabbit, but also Tika and POI (details below).
Also, Jukka Zitting has helped organize a NoSQL meetup in Oakland starting tonight where Bertrand Delacretaz will talk about JCR.
Bertrand Delacretaz: Life in Open Source communities: Open Source communities often seem to have their own unwritten rules of operation and communication, their own jargon and their own etiquette, which sometimes make them appear obscure and closed to outsiders. In this talk, we'll provide recommendations on how to get touch with, and how to join, Open Source communities. Based on ten years of experience in various Open Source projects, we will provide practical information on how to communicate effectively on mailing lists, how to formulate questions in an effective way, how to contribute in ways that add value to the project, and generally how to interact with Open Source communities in ways that are mutually beneficial. This talk will help Open Source beginners get closer to the communities that matter to them, and help more experienced community members understand how to welcome and guide newcomers.
Carsten Ziegeler: JCR in Action - Content-based Applications with Jackrabbit: The Java Content Repository API (JCR) is the ideal solution to store hierarchical structured content, and to develop content-oriented applications. This session provides a practical introduction to help you get started using JCR in your own application. To demonstrate the basic architecture of such applications, a sample content-based application will be developed during the session. Basic techniques will be explained, including navigation, searching, and observations, using the Apache Jackrabbit project.
Embrace OSGi - A Developer's Quickstart: In theory, the first choice for highly modular, dynamic, and extensible applications is OSGi technology. The theory sounds very tempting, but what about the real world? Starting with the basics of OSGi, this session is focused on practical examples, tools, and procedures for a rapid adoption of OSGi in your own projects. Learn how to avoid the typical traps and how to get the most out of OSGi
Felix Meschberger: Rapid JCR applications development with Sling: Apache Sling is an OSGi-based, scriptable applications layer, using REST principles, that runs on top of a JCR content repository. In this talk, we'll see how Sling enables rapid development of JCR-based content applications, by leveraging the JSR 223 scripting framework. We'll also look at the rich set of OSGi components provided by Sling. We will create a simple application from scratch in a few minutes, and explain a more complex multimedia application that does a lot with just a few lines of code. This talk will help you get started with Sling and understand how the different components fit together.
Jukka Zitting: MIME Magic with Apache Tika: Apache Tika aims to make it easier to extract metadata and structured text content from all kinds of files. Tika is a subproject of Apache Lucene, and leverages libraries like Apache POI and Apache PDFBox to provide a powerful yet simple interface for parsing dozens of document formats. This makes Tika an ideal companion for Apache Lucene, or for any search engine that needs to be able to index metadata and content from many different types of files. This presentation introduces Apache Tika and shows how it's being used in projects like Apache Solr and Apache Jackrabbit. You will learn how to integrate Tika with your application and how to configure and extend Tika to best suit your needs. The presentation also summarizes the key characteristics of the more widely used file formats and metadata standards, and shows how Tika can help deal with that complexity. The audience is expected to have basic understanding of Java programming and MIME media types.
Paolo Mottadelli: Apache POI recipes: The Apache POI project provides Open Source Java APIs for the manipulation of Microsoft Office format files. It was developed to provide OLE2 Compound Document format support. POI support for the new format was necessitated by the proliferation of new Office Open XML (OOXML) documents, due to its standardization. As a result, a common challenge emerged for projects that leverage POI to read and write Excel, Word, and PowerPoint documents: supporting the new format while maintaining backward compatibility with the earlier one. This session provides an overview of how the new POI architecture makes that challenge easier, using the common interfaces package and their double implementation. Participants will also learn about the main new features provided by POI towards support of the new OOXML format. To demonstrate POI's features, this session will also drive through a collection of practical recipes to solve the tough problems of integrating Office documents in your enterprise applications.
