1 Metalib and XML 2005 LITA National Forum (c) 2005, M. McKenna, UC Regents X-Server integration with the CDL Common Framework Using SOAP and XML to access Metalib LITA National Forum, October 1, 2005 Michael McKenna, CDL

2 Metalib and XML 2005 LITA National Forum (c) 2005, M. McKenna, UC Regents Overview: Metalib X-Server (/X) Currently supports basic services XML interface Modeled after Web Services (request/response) Core interface to MetaLib Data presentation in other application E.g., a university portal or an institution’s courseware management system

3 Metalib and XML 2005 LITA National Forum (c) 2005, M. McKenna, UC Regents (/X) Basic Interface Login User Authentication / User Affiliation Retrieve Resources Search Resources Retrieve Search Status Report Combine Result Sets Retrieve Search Results

4 Metalib and XML 2005 LITA National Forum (c) 2005, M. McKenna, UC Regents (/X) Upgrades /V Version 3.11 to 3.12? 196 files changed – for one instance (UCOP) 2,354 files changed – across all campuses Upgrade script saves and marks changed files “diff” and decide to keep changes or modify. Merge to recreate prototype interface /X Does not touch our UI May require modifications to Common Framework (CF) Manager Layer Generally, existing CF functionality is left unchanged /V = vanilla html interface/X = X-Server XML interface

5 Metalib and XML 2005 LITA National Forum (c) 2005, M. McKenna, UC Regents (/X) Development Methodology /V Cannot use CVS easily Cannot see UI changes unless Metalib can see files Cannot have unlimited Metalib instances Be careful not to trash other’s work! Keep close tabs on changes Do regular file system backups /X Use CVS and Java IDE Integrate with Common Framework development environment /V = vanilla html interface/X = X-Server XML interface

6 Metalib and XML 2005 LITA National Forum (c) 2005, M. McKenna, UC Regents (/X) Development Methodology /V Example – to customize simple search, change all the following: quick-1, quick-2-end, quick-3- body, quick-details, quick-1- body, quick-2-end.orig, quick- 3-head, quick-details-info, quick-1-head, quick-2-head, quick-3-js, quick-full, quick-1- tail, quick-2-tail, quick-3-no- results, quick-help, quick-1- toolbar, quick-2-toolbar, quick- 3-tail, quick-help-main, quick- 1-toolbar-pd, quick-2-wait, quick-3-toolbar, quick-js, quick-2, quick-3, quick-8- body.spa, quick-main-help /X To brand or create new simple search, change only of the following: search.jsp /V = vanilla html interface/X = X-Server XML interface

18 Metalib and XML 2005 LITA National Forum (c) 2005, M. McKenna, UC Regents /X Issues Limited buffer sizes in ML /X Being fixed by ExLibris using Apache for 3.13 Limited number of databases that can be searched Same limits as MetaLib – communicate in ConnectService Balance Speed vs. Coverage Response time, time-outs Communicate parameters in ConnectService
