General

Media Center helps you manage, organize and view your files by maintaining a collection of properties on a per-file basis. Each file managed by Media Center belongs to a particular media type (eg. audio, video, image), and each media type has a predefined set of properties available and valid for use.

Examples of file properties are Artist, Album and Genre for audio files, Actor, Director, and Aspect Ratio for movies, and Width, Height and Focal Length for images.

Initially, a file's properties are imported when the file is imported, or created when the file is created by Media Center (e.g. when ripping a CD or DVD). Typically, this data comes from a file's internal metadata (commonly referred to as tags), or is looked up from external databases. In addition, several library tools are available to assist in creating or modifying properties and tags.

Media Center can also save a file's properties to the internal metadata within the physical file itself. These tags are then available for use by other programs that support the specific file types. The tags supported by a given file type are file type-specific, but there is often commonality or overlap in various media or file formats. Media Center helps manage this by automatically mapping essentially similar tags with different names into a standard set of properties.

In addition, Media Center allows creation of an almost limitless number of custom (or user) properties. This allows for managing information about files that is not predefined by Media Center or by a given format's standard tags. These custom properties may also be saved to a file's tags, should the format support user-defined or extensible tags.

Saving file properties to the physical file allows tags to be re-imported by Media Center, and used by other programs on a variety of systems. While typical metadata consumes a trivial amount of extra disk storage (relative to the file's size), larger metadata such as cover art, lyrics or extensive notes may be more noticeable, especially when files are exported to smaller devices such as handhelds. See Save File Properties in Disk Files for more information.

The table below shows the standard default properties available in Media Center. File properties are listed and managed under:

 Tools > Options... > Library & Folders > Manage Library Fields...

Note here that properties are called fields. This is primarily a technical and pedantic distinction. The terms properties, fields, and tags become synonymous in common language, but do nonetheless maintain distinct meanings. It might help to think of a spreadsheet, where column headers are fields, rows are files, and a row of individual cell values are the file's properties. If each row were saved to an external file, the row's cells would be called tags.

As briefly mentioned above, properties help manage and organize related files. They can also be searched. In all of these, either directly or indirectly, one or more library fields is used in the construction.

When used in expressions or searches, a field is expressed by surrounding its name with square brackets. For example, Album Artist is written and used as [Album Artist]. Field names are case-insensitive, meaning there is no distinction between upper- or lower-case letters. They are typically written in camel-case to help make them more distinguishable, especially in complex expressions.

Field Specifications

Library Fields.png

Each field in Media Center has several defined characteristics. These are shown in the marked-up example dialog to the right, Manage Library Fields. Each field:

  1. Has a standard, unchangeable name
  2. Has a display name and its plural version (not currently shown in table)
  3. Is valid for the specified media/file types (Audio, Image, Video, Data, TV)
  4. Is either "User" data, or is automatically calculated via expression
  5. Stores a particular type of data (see Field Data Types)
  6. May or may not be relational (no default fields are currently relational)
  7. Has rules about its editability (see Field Edit Types)
  8. May have a list of acceptable values
  9. May be stored in file tags (when possible)
  10. May have one or more search keywords used for queries
  11. May be searched by default when performing search queries
  12. May be hidden from normal view/usage (these field names are shown in italics in the Media Center Predefined Fields table below)


Field Data Types
Data Type Description
String An unformatted sequence of characters.
Integer A whole number (no decimal portion).
Decimal A floating point number.
Percentage A decimal from 0 to 1 indicating 0% to 100%.
List A semicolon-separated list of strings.
Date A complex type that is either date-only, or date and time. (TBD: need refs)
Unknown An unspecific catch-all type, not specifically defined.


Field Edit Types
Edit Type Description
Standard A free-format, editable field.
Clear-only A clear-only field, whose value is set or updated by Media Center.
Large A free-format, editable field, used for large data (e.g. lyrics, notes, descriptions). (TBD: recommended for data larger than XXX characters).
Not editable A non-editable field.
File A file-path specification field.
5 Star A selectable, 5-star graphical field, typically used for ratings.
Calculated, Editable A calculated, editable field, whose initial value is automatically set.
Calculated,
Not editable
A calculated, non-editable field whose value is automatically set.


Predefined Fields

The table below lists Media Center's default fields. The rows list the available fields, and the columns indicate how the field is defined, and gives a brief explanation of the fields usage or meaning. Where applicable, additional links and field-specific information is also listed. The value for some fields is calculated by Media Center. When possible, the expression used to derive this value is also shown. In some cases, this value may be modified. Beneath a field name is a list of the default Search Keyword(s), if available, which are used for field-specific searching within Media Center.

(TBD: in the source code, fields are grouped by certain categories (eg. statistics). are these useful to show?)

Note: Some fields are used internally by Media Center to maintain state information, and are not viewable in panes, categories, or the Tag Action Window. These are typically configured through various options and settings dialogs.

Custom Fields

Custom fields may be added with the Add New Field button in the Tools > Options > Libraries & Folders > Manage Library Fields... dialog.

Tag Import Options

Media Center provides a few options for the importation of tags for some file types. These options are available via Plug-in Manager > Input for the given file type. Select the Configure button for a given type, if available.

For images and video, Media Center will fill in the Album field with the year of the image or video (if the album field is otherwise empty). This puts a reasonable value there when importing directly from a digital camera. (TBD - should this be moved? Is it comprehensive wrt other types/fields?)

Classical Music

The tagging of classical music is unfortunately more complex and standards are lax. See Tagging Classical Music.

Photos

For more comprehensive information on tagging photos, see Photo Tagging.
