Figure 6.7 RDF notation vs. "traditional" notation with ID and label and short name
(GreenDelta TC, unpublished).

Structuring information in this way promises to make it readable by many
different machines, and even to some extent by humans, thereby allowing col-
laboration and data sharing. This is very interesting for LCA software (see also
the interoperability trend, below); import and export of LCA information in
RDF have been discussed and also implemented for earthster, 2011 1314 , and
also discussed as a possible future for LCA data [UNEP 2011].
However, it is still questioned whether RDF and the semantic web can be
used for managing large amounts of data. Figure 6.7 shows the two reference
units, meter and kilogram, as they are used in the openLCA format converter,
in "traditional" notation (just UUIDs, longname, shortname) and in RDF
notation.
