• CVS short description
• CVS Server
• CVS GUI clients
• Other revision control systems
• CS-RCS
• EDMS
• Proposals of CrossGrid Repository Architecture

3
Possible software configurations

• CVS CVS GUI Client
• CVS CVS Web Client
• CS-RCS (Component Software Revision Control
  System)
• EDMS (Engineering Data Management System)

4
CVS Concurrent Versions System

• The dominant open-source network-transparent
  version control system.
• Useful for everyone from individual developers to
  large, distributed teams
• its client-server access method lets developers
  access the code from anywhere there's an Internet
  connection,
• its client tools are available on most platforms.

5
CVS CVS GUI Client

• CVS GUI clients exist for many platforms
• WinCvs for Windows
• MacCvs for MacOs
• gCVS for Unix
• Available at http//www.wincvs.org

CVS CVS Web Client

• It allows users to edit files in a CVS
  repository, using only a web browser.
• Available at http//stud.fh-heilbronn.de/zeller/c
  gi/cvsweb.cgi/

CS-RCS (Component Systems-RCS)

• Based on the widely used GNU RCS,
• Fully integrated with the Windows Explorer,
• Provides the most intuitive and easy-to-use
  configuration management and change control
  solution in the market,
• Supports multi-platform workgroups, making it the
  ideal solution for sites that share common files
  on UNIX and Windows platforms.

10
CS-RCS - continued

• Handles all types of documents including
• program files,
• project files,
• resource files,
• HTML documents,
• MS-Word documents,
• pictures and drawings.

11
CS-RCS - continued

• Uses any file server or local drive to store the
  archive repository.
• Network connection to the archive repository can
  be LAN, corporate wide-area network (WAN),
  dial-in connection (RAS) and the Internet.

12
CS-RCS - Integration with Windows tools

• CS- RCS is fully integrated with MS-Word
• There is a special menu entry - RCS - which will
  be added to MS-Word. Integration is automatic
  when CS-RCS is installed.
• All features can be accessed from MS-Words
  toolbar, making CS-RCS part of users everyday
  desktop.
• Whenever a document is checked-in, CS-RCS updates
  MS-Word internal variables. It enables displaying
  the accurate revision number of important
  documents.

13
CS-RCS - Integration with Windows tools
(continued)

• CS-RCS implements the Microsoft Common Source
  Code Control API. (Also called the SCC API or
  SCCI.) This API enables seamless integration of
  CS-RCS with many development tools for Windows,
  including
• Microsoft Visual Studio products (including
  Visual C and Visual Basic)
• CA Visual Objects
• Allaire ColdFusion

14
CS-RCS - Integration with Windows tools
(continued)

• Sybase PowerBuilder
• Rational Rose
• VisualAge for Java
• MERANT Micro Focus Net Express
• Forté C Application Environment
• Programmers editors Multiedit, Codewright, Zeus
  
• Bug Tracking Tools SeapineTestTrack

15
CS-RCS - Change Synchronisation Methods

• Exclusive locking model - All work files are
  read-only. A user must lock the file in order to
  edit it. When the user check-in the changes, he
  must unlock the file in order to enable other
  users to edit it.
• Concurrent changes model (CVS) - All users may
  always edit all files. When a file is checked in,
  CS-RCS merges the edits automatically into the
  repository. In case of conflicts, CS-RCS
  highlights them to assist the user in solving
  these conflicts.

16
CS-CVS - Windows front-end for the GNU CVS

• The CS - CVS (Component Software - CVS) solution
  consists on two products
• CS-RCS which provides full support for local RCS
  and CVS repositories. This version supports local
  CVS repositories.
• CS-CVS which is an add-on product for CS-RCS.
  CS-CVS provides support for the CVS client-server
  architecture. (That is, the pserver, ntserver,
  rsh and ssh protocols.)

17
CS-CVS - Windows front-end for the GNU CVS
(continued)

• CS-CVS add-on should be used to
• Access remote repositories over corporate network
  or the Internet.
• Gain better security on access to repository
  files.
• Access legacy CVS repositories.

18
CS-RCS - Conclusion

• The major benefits of CS-RCS
• Powerful CS-RCS implements the major
  requirements of version control and configuration
  management systems.
• Simple CS-RCS is simple to learn and easy for
  daily use. There are no daily administrative
  operations which require a full-time system
  administrator.
• Unlimited There is no limit to the number of
  users, projects, files or revisions. The only
  limit is the repository server disk space.

19
CS-RCS - Conclusion (continued)

• Reliable Over 20,000 users in more than 2000
  large and small organisations in 30 countries
  have been using CS-RCS since its first release
  in 1997.
• True Open System The archive files are stored
  using the public GNU RCS format. This format can
  be imported by a majority of tools in today's
  market.

EDMS - major subsystems -continued

• EDMS - Engineering Data Management System
• CDD - CERN Drawing Directory application - a WWW
  utility for management of graphical documents
  (drawings)
• CADIM / EDB and MP5 - two commercial
  applications using the Oracle database system

23
EDMS - Documents Management

• Document Definition
• Managing Document in a Structure
• Document Lifecycle Release Procedures, Versioning

24
EDMS - Document attributes

EDMS - Document Search

• Search mechanism allows a user to search for any
  text document or drawing in any project or only
  in a specific project using
• number
• title, abstract, keyword
• authors
• document type
• year, modification date
• status.

EDMS - Structures
These structure nodes are called Projects in the
EDMS.
When the amount of data grows, it is convenient
to structure the documents. This has several
advantages - It is easier to find documents
(structure document meta data gives lots of
search possibilities) - It is possible to group
documents that are logically linked.

EDMS - Release procedures

• Release procedure defines
• possible document statuses,
• possible transitions and required user privileges.

CrossGrid Repository Architecture Proposal (1)

• First solution
• Local repository servers for each software module
  and documents
• Central server in Karlsruhe (mirror of all local
  repositories software documents)
• CVS server in Cyfronet (mirror of Karlsruhe
  repository software documents)

33
CrossGrid Repository Architecture Proposal (2)

• Second solution
• One central repository server in Karlsruhe for
  all software modules and documents (without local
  repositories)
• CVS server in Cyfronet (mirror of Karlsruhe
  repository software documents)

34
CrossGrid Repository Architecture Proposal (3)

• Third solution
• Local repository servers for each software module
  and documents
• Central server in Karlsruhe (mirror of all local
  repositories software documents)
• Documents Repository in Cyfronet (all
  deliverables, reviews, minutes, etc. without
  software source codes) access through CrossGrid
  WWW sites.

35
CrossGrid Repository Architecture Proposal (4)

• Other solutions - discussion
