Seventh Framework Programme Fp7-Ict-2009-6 SEVENTH FRAMEWORK PROGRAMME FP7-ICT-2009-6 BlogForever Grant agreement no.: 269963 BlogForever: D2.1 Survey Implementation Report Editor: Silvia Arango-Docio Revision: Draft V1.0 Dissemination Level: WP2 Author(s): S. Arango-Docio, P. Sleeman, H. Kalb Due date of deliverable: 31/08/2011 Actual submission date: Start date of project: 01 March 2011 Duration: 30 months Lead Beneficiary name: University of London Abstract: This report outlines a principal study aiming to inform the development of preservation and dissemination solutions for blogs. To achieve this, the study encompassed: [i] a user survey exploring the aspects of blog preservation and blogging practices in general; [ii] an investigation into the use of tools and technologies within the Blogosphere; and finally [iii] an inquiry into the recent theoretical and technological advances for analysing blogs and their networks. The results of the study, as summarised in this report, enable addressing the objectives pursued as part of the D2.1 deliverable of the BlogForever project. More specifically, this report comments on: [a] common weblog authoring practices; [b] important aspects and types of blog data that should be preserved; [c] the patterns in weblogs structure and data; [d] the technology adopted by current blogs; and finally [e] the developments and prospects for analysing blog networks and weblog dynamics. As an account for the conducted work this report includes implementation details and adopted ethical guidelines. The results of the inquiry are discussed within the context of BlogForever – offering directions for further development of the project.

  • CHAPTER 12 Making Your Web Site Mashable
    CHAPTER 12 Making Your Web Site Mashable This chapter is a guide to content producers who want to make their web sites friendly to mashups. That is, this chapter answers the question, how would you as a content producer make your digital content most effectively remixable and mashable to users and developers? Most of this book is addressed to creators of mashups who are therefore consumers of data and services. Why then should I shift in this chapter to addressing producers of data and services? Well, you have already seen aspects of APIs and web content that make it either easier or harder to remix, and you’ve seen what makes APIs easy and enjoyable to use. Showing content and data producers what would make life easier for consumers of their content provides useful guidance to service providers who might not be fully aware of what it’s like for consumers. The main audience for the book—as consumers (as opposed to producers) of services—should still find this chapter a helpful distillation of best practices for creating mashups. In some ways, this chapter is a review of Chapters 1–11 and a preview of Chapters 13–19. Chapters 1–11 prepared you for how to create mashups in general. I presented a lot of the technologies and showed how to build a reasonably sophisticated mashup with PHP and JavaScript as well as using mashup tools. Some of the discussion in this chapter will be amplified by in-depth discussions in Chapters 13–19. For example, I’ll refer to topics such as geoRSS, iCalendar, and microformats that I discuss in greater detail in those later chapters.

  • Integrating with Blogs
    CHAPTER 5 Integrating with Blogs Blogs (also known as weblogs) have become lightweight, general-purpose platforms for publication, self-expression, and collaboration. Bloggers push the limits of new-media production, especially in the area of integration, because they want ultimately to discuss anything they can see or think or hear—without any effort, of course. Because you can directly tie blogs in with other systems—often without any programming on your own part—you’ll now study how to combine blogs with other applications and data sources. In this chapter, I cover end-user functionality that lets you publish content to a blog from a web site or a desktop application. In Chapter 7, you’ll study how you can program the relevant web APIs to read and publish blog content. I close this chapter by applying lessons from blog integration to wikis, which I believe are ripe for a similar type of remixing. In this chapter, you will do the following: * You’ll learn how to configure your WordPress or Blogger blog to receive pictures from Flickr through Flickr’s Blog This button. * You’ll study the mechanisms behind blog integration by studying how it’s done with Flickr. * You’ll learn how to use a desktop blogging client to take advantage of a richer writing environment for blogging. * You’ll see how the combination of syndication feeds and blogging can be recursive (that is, how content from blogs can be refashioned into new blog entries). * You’ll experience the forward-looking social browser integration of Flock, which combines a Web browser, Flickr photos, and blogging all in one user interface.

  • In the Spirit of Georgeʼs Request for Feedback from The
    In the spirit of Georgeʼs request for feedback from the employees I tossed together most of the things that buzz around my head as things we could do to take advantage of the fact we online media not print media. These are all technology related ideas and suggestions that apply both to efficiency issues internally and to B2B and consumers. Syndication Syndication on the web has formalized around RSS feeds. Aggregators like Google News use this, and users use this via RSS client software or aggregators like Google Reader. RSS clients exist for almost every platform from the PC to the iPhone. Optimally every page on the site that lists content should be available as an RSS feed including search results. For instance, I should be able to subscribe to an RSS feed for the “Europe” regional portal page, or the Terrorism Weekly, or the search results of the term “Putin”. Aggregation The flip side of pervasive syndication via RSS on the Web is the ability for users to specify feeds from other sites they would like to look at in what place or for sites like ours to pull content or links to content via RSS that is in context to our content. For instance, titles to recent NYTIMES articles on Europe on our Europe regional portal page. Links and References Weʼve been very good internally at taking advantage of our existing content and linking to previous articles in context within a new article. What we donʼt do so much is link to outside sources of information within our articles or provide links to relevent information as a footnote to articles.

Abstract The Web is increasingly important for all aspects of our society, culture and economy. Web archiving is the process of gathering digital materials from the Web, ingesting it, ensuring that these materials are preserved in an archive, and making the collected materials available for future use and research. Web archiving is a difficult problem due to organizational and technical reasons. We focus on the technical aspects of Web archiving.
