  6. OpenG’s Packages on SourceForge OpenG projects hosted on SourceForge release packages through SF’s package release system • Packages are available at over a dozen mirrors worldwide • Mirrors have predictable URLs OpenG Packages are always online! OpenG Group Meeting

  7. What’s a Package Directory? A Package Directory is a listing of packages. It points to the URLs of packages in the repository. It also points to the URLs of other package directories. OpenG Group Meeting

  8. A “Web” of Packages Package Directory Contains  Package URLs  Directory URLs OpenG Group Meeting

  9. The “Web” analogy • As Web pages link to other Web pages, package directories link to other package directories • As web pages link to downloadable files, directories link to downloadable packages OpenG Group Meeting

  10. What’s a Package Directory Service? The Package Directory Service is a way of locating packages and directories of packages over a network. To continue the web analogy think of it as a search engine. OpenG Group Meeting

  11. Some Implementation Details • Package Directory Files • Directory Links • Package Cache OpenG Group Meeting

  15. OpenG Packages - User Perspective OpenG Group Meeting

  16. Recap • Package Directory Files are similar to Web pages (which link to non-Web page files and other web pages) • The Package Directory Service is a crawler that is able to search within some defined scope for available packages. • Packages are cached locally when downloaded and may be installed or uninstalled to quickly switch between development system and library configurations.
