6.1.5.1 Ideas that are No Longer Trends

SaaS: Software as a Service (SaaS) means that users do not buy a software
license, but rather are paying for the service of using the software. SaaS is
attractive if there are high license costs (which is currently the case, for LCA
software). However, in the business field, there is also some reluctance to using
an external service for managing company data that is seen as sensitive and
critical - which is the case for company-specific LCA data that explains for
example emissions of a company-run industrial process.
Semantic Web: Semantic web is the idea to describe information, or content,
in a flexible way that is readable by different machines. A Resource Description
Framework (RDF) language is used for describing the information, in triples:
each information "piece" has a subject, a predicate, and an object. The WWW
consortium provides an instructive example [W3C 2004]:

http://www.example.org/index.html has a creator whose value is John Smith
could be represented by an RDF statement having:

• a subject http:/ /www.example.org/index.html
• a predicate http://purl.0rg/dc/elements/l.l/creat0r
• and an object http://www.example.org/staffid/85740
