* Service Types. A service type is defined by a tModel. Multiple businesses can offer 

the same type of service, as defined by the tModel. A tModel specifies information such as 

the  tModel  name,  the  name  of  the  organization  that  published  the  tModel,  a  list  of 

categories that describe the service type, and pointers to technical specifications for the 

service  type  such  as  interface  definitions,  message  formats,  message  protocols,  and 

security protocols.

2.3 UDDI and Golden Pages? 

Golden Pages is currently primarily a  discovery  service. It functions as a simple listing 

of businesses in Ireland, sorted by business type and, in the case of the print edition, by 

area. The idea of adding  discovery  and  integration  to this service is an appealing one 

and, since the UDDI protocol is an open standard which is there to be used, integrating 

the Golden Pages into UDDI in some way was the initial goal of this project. To this end, 

two  options  presented  themselves.  The  first  route  would  be  to  set  up  an  independent 

Golden  Pages  UDDI  registry,  using  the  UDDI  system  of  Nodes,  Business  Entities, 

tModels  et  al.  While  maintaining  the  simple  functionality  of  the  original,  businesses 

would be given the opportunity to greatly increase the amount of information they could 

supply  about  themselves  and  their  products  and  services  on  the  web.  Additionally, 

because UDDI is an open standard, there would exist the possibility of later integration 

with  other   Yellow  Pages   UDDI  registries  around  the  world,  should  they  exist.  The 

second  option  would  be  to  set  up  the  Golden  Pages  as  a   Registrar ,  a  third party 

company which would enter and maintain its clients` details on one of the global UDDI 

registries. 

In the end, neither of these ideas proved feasible. The private registry idea was hampered 

by the fact, although tools such as jUDDI (an Apache project) and UDDI4J (by IBM) for 

creating  registries  do  exist,  they  are  both  very  much  in  the  developmental  stage  and 

documentation  in  each  case  is  sparse.  Furthermore,  both  implementations  run  on  Java 

servlets, the recommended implementation of which, Tomcat, proved very unreliable and 

difficult

there is no stable release of jUDDI, only automated nightly CVS  snapshots , and the last 

major release of UDDI4J was in May of 2002. If and when development ever picks up on
