The Data Explorer View

The Data Explorer view is available for all Bitstreams (“files”) in an Item which have gone through the curation process. It allows users to view the data contained in a file without having to download the entire data and explore it locally on their computer's filesystem.

Accessing the Data Explorer

To access the Data Explorer view to explore a file's data, the user must access the Item page of its parent Item. The system will show a “Explore Data” option next to all files which have been curated.

The user may select the “Explore Data” option to access the curated data. The system will then show a series of tabs, one for each logical table contained in the file. The user may select a tab and the system will show only that table.

The Options Toolbar

Data Explorer Options Toolbar

Atop of the visualization area, there is a toolbar with 3 buttons:

Download Current Data

This option allows the user to download the data currently displayed in the selected tab to the local filesystem. This is useful for retrieving relevant parts of data tables which correspond to the filters currently specified by the user.

Download Current Sheet

This option allows the user to download the table containing the data which corresponds to the table currently selected (disregarding any filters that may have been applied).

Download Workbook

Retrieve the whole workbook containing the whole data (with one sheet per tab shown in the data explorer page).

All downloaded files will contain the relevant table metadata for each table they include, the headers and data rows.

The download format is Office 97 Excel Spreadsheet (*.XLS) for maximum compatibility.

Viewing Metadata for the table

The user can view the metadata associated to a specific table by clicking the corresponding option.

View Metadata

Filtering Data

The Data Explorer view also allows users to filter the data that they want to view. To do this, users may specify filters to apply to the data by combining sets of restrictions on data columns.

Filtering Option in the Data Explorer view

The restrictions use a series of operators, such as ”>”, ”>=”, ”=”, or “includes” (for textual values). For each restriction, the user must specify the target column, the operator and a value to be used as the argument parameter.
