21.2 Challenges Addressed
UNESCO has a large volume of data of many different kinds which describes the
sites which have been inscribed. This data must be able to be used in future on
order that, for example, UNESCO in the future can compare the state of a site with
the original state of the site. This has to be achieved despite the certainty that the
instruments used to measure the site will be different; the way the data is captured
will be different; the way in which the data is encoded will be different; the software
used to analyse the data will be different.
21.3 Preservation Aim
Preserve all steps required to create associated digital virtual reconstructions from
real tangible cultural heritage objects.
Find possible solutions to assist Member States on the preservation of cultural
heritage digital data.
21.4 Preservation Analysis
The variety of data which UNESCO must collect from world heritage sites present
a great challenge because of their diversity. Many datasets are used with propri-
etary applications; complex workflows are used to create the higher level products.
UNESCO must be able to compare modern measurements of heritage sites with
older measurements in order to see if there has been a degradation in the site. Both
the measurements techniques and data encoding change over time, therefore it must
be possible to combine data from various sources. The better option is therefore to
describe the digital encodings in as great a depth as possible.
