Often the "tables" will actually recede to a single table only. In a way DD datasets are stand-alone databases.

GEDCOM files can also contain attributes such as physical description, occupation, and total number of children; unlike events, attributes generally cannot be associated with a specific time or place.

Some genealogy programs, such as Gramps and The Master Genealogisthave elaborate database structures for sources that are used, among other things, to represent multi-person events.

When databases are exported from one of these programs to GEDCOM, these database structures cannot be represented in GEDCOM due to this limitation, with the result that the event or source information including all of the relevant citation reference information must be duplicated each place that it is used.

This duplication makes it difficult for the user to maintain the information related to sources.

This flexibility has led to a great deal of ambiguity, and has produced the side effect that some genealogy programs which import GEDCOM do not import all of the data from a file. Such relationships can only be represented using the generic ASSO tag used for any type of relationship. Ordering of events that do not have dates[ edit ] The GEDCOM specification does not offer explicit support for keeping a known order of events.

In many cases the sequence of events can be derived from the associated dates.

But dates are not always known, in particular when dealing with data from centuries ago. For example, in the case that a person has had two relationships, both with unknown dates, but from descriptions it is known that the second one is indeed the second one.

In Aldfaer [49] for instance, the sequence depends on the ordering of the data by the user alphabetical, chronological, reference, etc.

Lesser-known features[ edit ] GEDCOM has many features that are not commonly used, and hence are unknown to some people.

Embedding multimedia directly in the GEDCOM file makes transmission of data easier, in that all of the information including the multimedia data is in one file, but the resulting file can be enormous. Linking multimedia keeps the size of the GEDCOM file under control, but then when transmitting the file, the multimedia objects must either be transmitted separately or archived together with the GEDCOM into one larger file.

Call centre challenges

Support for embedding media directly was dropped in the draft 5. The preferred record is usually listed first. The standard does not specify in any way that the contents must be consistent. The only way to reveal such inconsistencies is by rigorous validation of the content data.

Metadata provide additional information about a certain file, such as its author, creation data, possible copyright restrictions or the application used to create the file.

The way metadata can be used in PDF files is described on this page.
