Metadata, Indexes

New Types of Elements of the Metadata Scheme: Data and HTML

In version 6.0 of the dLibra system, there are new possibilities regarding the editor’s descriptions of digital objects. Apart from standard text attributes (available so far), the editor can use data and HTML attributes.
HTML-type attributes make it possible to to put basic HTML tags in the attribute text, which allows creating untypical values (a different style or information structure, emphasizing fragments).
In the case of data-type attributes, the editor introduces a time range or an individual date, so users of the digital library can filter objects by time range.
Version 6.0 of the dLibra system has an in-built mechanism of automatic recognition of date ranges. For example, if the user types in “the 1^st half of the 12^th century”, the system will suggest an appropriate date range. Your old values will also be processed automatically, and appropriate ranges will be proposed.
If our algorithm does not recognize something, it will let you know about it. That, however, is an extremely rare event – the results of our tests have shown that only a few percent of dates are not recognized by our algorithms.

As regards browsing attribute value indexes, there are now more options than just paging and browsing alphabetically. With version 6.0 of the dLibra system, we introduce improved alphabetical browsing – there is a new function of filtering values by a search phrase, which allows greater precision in the case of huge indexes.
