Embedded links are not useful for data that cannot be overwritten, such as for read only data or data owned by others, and this is what motivates the use of externalised links in systems such as Microcosm, despite their greater chance of link error. 3.4 Regular updates This strategy is preventative, if links are issued with the new documents, or corrective otherwise. Information changes at predictable intervals, i.e. information is issued in editions . To Embed or Not to Embed . If the links are bound too closely to the documents, they cannot be applied to new documents.
Microcosm takes a slightly different approach however.
The system should allow the import and use of any data format, including temporal media. This can be read as a multi media requirement, although it covers issues like legacy data formats and encryption techniques as well. No context found. H. C. Davis. Communications of the ACM, vol.
