Portals and CMS – Why You Need Them Both paul. browning@bristol. ac. uk
Route map • • • Environmental scan What is a CMS? What is a Portal? How does the CMS relate to the Portal? Demo (maybe some magic, if there’s time) Some reflections
True confessions … • We don’t (yet) have a centrally supported CMS • We don’t have an institutional portal • We plan to have made decisions on both by August 2002 • What follows is a mix of vaporware, prototypes and incomplete understanding
Environmental scan I • From the viewpoint of a research-led University say five years ago: – The Web is not life threatening – The Web is another hassle – what is it replacing? – We’re over-subscribed with well qualified candidates • “It’ll be very expensive to put a server in Mexico”
The pre-millennial Web • A hobby for someone • Apache on a file system • Highly manual methods of content creation and maintenance • In effect a read-only medium • A spot of Perl • A Webmaster • Let the “professionals” get back to serious computing • “Three clicks away from crap”
Environmental scan II • From the viewpoint of a research-led University today: – DDA 1995 & SENDA 2001 – September 2002 – Perhaps the Web is career threatening? • Let’s re-do the Web to make it accessible • Let’s re-paint the Forth Road Bridge again and again • Let’s work harder rather than smarter
The pre-millennial Web can’t scale • The pre-millennial Web is broken • We need a Web Content Management System: – A web site is like a dog – it’s for life – We need to move beyond the “Freds in the Shed” – We need a dynamic, automated, write-enabled, de-skilled Web …. . – …. . supported by a multi-skilled Web Team (who never touch the content)
The content life cycle
The defining features of a CMS • A CMS has substantial overlaps with DMS, VLEs, Groupware, Weblogs, Portals …. CMS Portal • Browning & Lowndes (2001) – Versioning (checkout/in, rollback) – Workflow – Integration (“joinupability”) √ √ √ • Not a finished product; a concept, a set of processes, a framework x x √
The most desirable features of a CMS (IWMW, 2000) 1. Template-based self-service authoring for non-technical content providers (‘frictionless publishing’) 2. Roles-based security 3. Workflow management - submit, review, approve, archive 4. Integration with existing data/databases and user authentication systems 5. Metadata management 6. Flexible output - write once, publish many times

CMS in 2002 • If you haven’t got one or aren’t thinking about getting one then you either: – Have a web site of less than 100 pages or – Have a web site with less than three authors or – Are probably dead meat
Portal = MLE = VLE + CMS Content Management System (CMS) e. Strategy = an institutional understanding of these relationships?
What is a portal? A portal: • Aggregates information and applications one stop shop • Is personalised or ‘groupilised’ one size does not fit all • Aspires to be your desktop on the Webtop
Examples of portals TABS • • • Law Intranet Blackboard Amazon Tesco LSE for You CHANNELS or PORTLETS

Some reflections • • • CMS Portal Siloware vs. Glueware Senior managers Who’s the CTO? IWMW 2003 Putting lipstick on bulldogs
CMS Portal
How we’d like things to be …. SIS Digital Library Portal framework CMS DNER Agnostic, open standards compliant – plugs and sockets
… but how it often is Siloware Digital Library SIS Portal framework DNER CMS just sockets – “do it our way”
Doncha love Senior Managers? • Why can’t we just use Google? • We don’t need a portal – we just need a well -designed Web site • Our SIS is ‘Best of Breed’ so it must be good • Why can’t we just use Outlook and Exchange?
Who’s the CTO? • Your Director of IT Services? • UCISA? Siloware is often golfcourseware – “It gets sold to senior executives by smooth-talking sales executives who claim their products solve every conceivable business problem, is a doddle to install, standards compliant, holographic user interfaces, everything. ” • • • SCONUL? ALT? JISC? e. Envoy? Who’s the CIO? We need to be investing in glueware and the people who can use it
The Scaleable Web (IWMW 2003) • Making it easy for the end-user means more complexity behind the scenes • The increasing dynamic Web will start to fail as sites get busier • Who in your institution is looking at: – Load balancing – Clustering – Cacheing • Amazon & Tesco have • Overlaps with the GRID?
The technology is the easier bit "The worst thing you can do is to Webenable a bad process, " said Friedlein. "As a client once put it: 'There's no point in putting lipstick on a bulldog, '" he added.
