2.4. Metadata Search

Metadata Search is an option that allows you to search through all the IMDI files from a selected node down. When you first open the Metadata Search, there are two search options: Keyword Search and Advanced Search. There is also a count of how many sessions there are from the selected node down.

Keyword Search:This search is if you are not sure of the content of the corpus and just want to make generic wide searches on specific words, from the highlighted node down (Figure 2.4)
Metadata Search – Keyword Search

Figure 2.4. Metadata Search – Keyword Search


In Figure 2.4, the Chontal Corpus Node is selected as the top node for a keyword search. The keyword ‘food’ is entered into the search field. The search results in four hits on session files in the corpus. These are sessions with the word ‘food’ somewhere within the metadata.

AdvancedSearch:In Advanced Search, the structure of the metadata file is the basis for the search. Figure 2.5 shows the most basic option of Advanced Search: it shows two dropdown selections (A) and a free-text field (B). This search is on session name only; any text you enter into the free-text field will only search the session name field of your selected section of the corpus.

 The second drop down list offers: Names, Title, Date, Location, Project, Keys, Content, Actor, Resources and References. Choosing one of these will extend the search option following the structure of the metadata file.
 Figure 2.6 shows a two-constraint search (constraints are like filters that you apply to your search. The option "Add constraint" allows you to choose the number and type of constraints you need.): the first constraint searching on Location, Country, Mexico, and the second on Resources, MediaFile, Format, video/x-mpeg1. Run from the Dobes node, this search locates 79 results from a total 176 potentials.

 The (X) drop down is an option available only for "Actor" and "Resources" > "Media File" (drop down list after "Session"), which present more than one feature. For example, if you add a third constraint that has again an (X) drop down, you can choose: either letter (X), if you want to search for another feature of the same, for instance, actor; or another available letter, if, by contrast, you want to search for some feature belonging to a different entity.

Search results:No matter which type of search you use (keyword or advanced) your search results will be displayed as a list of imdi metadata files (Figure 2.6).
 Right clicking one of the results allows to:
 1. Show Session with Tree opens a new browser window with the selected IMDI file highlighted in the tree
 2. Show Session opens a new browser window with the content of the IMDI file
 3. Content search redirects you to the window Annotation Content Search (see 2.1)
