A representation of a Key/Encoded-Value pair is generated by concatenating the contents of the first four columns of a row that begins with an ampersand in the Matrix below. The ordering of KEV pairs is not important. Rows which have '#' in the first column are comments and should not be included in the representation.
The following data types are provided for the values of the Keys, which must be URL-encoded:
| <data> | Character string |
|---|---|
| <id> | Character string for an Identifier (Z39.88-2004, Part 1, Section 7) |
| <fmt-id> | Character string for a Format Identifier (Z39.88-2004, Part 1, Sections 12 and 13) |
| <m-key> | Character string for a Metadata Key (Z39.88-2004, Part 2, Section 7.1) |
| <url> | Character string for a URL |
| <date> | Character string representing a date to the complete date level of the W3CDTF profile of ISO 8601, of the form: [ YYYY-MM-DD | YYYY-MM | YYYY ] |
| <time> | Character string representing a date and time to the seconds level of the W3CDTF profile of ISO 8601, of the form: [ YYYY-MM-DDThh:mm:ssTZD | YYYY-MM-DD ] |
Abbreviations in column headings:
| Delim | Key | Equals | Value | Min | Max | Description |
|---|---|---|---|---|---|---|
| & | format | = | <data> | 0 | 1 | Mimetype of the image format to be provided as response. Default: image/jpeg |
| & | rotate | = | <data> | 0 | 1 | Integer. Rotates decompressed image by 90/180/270 degrees clockwise. Default: 0 |
| & | level | = | <data> | 0 | 1 | Integer. Where 0 is the lowest resolution with each increment doubling the image in size. Default: Max level of requested image, based on the number of Discrete Wavelet Transform (DWT) decomposition levels. |
| & | region | = | <data> | 0 | 1 | Format: Y,X,H,W. Y is the down inset value (positive) from 0 on the y axis at the max image resolution. X is the right inset value (positive) from 0 on the x axis at the max image resolution. H is the height of the image provided as response. W is the width of the image provided as response. All values may either be absolute pixel values (e.g. {100,100},{256,256}), float values (e.g. {0.1,0.1},{0.1,0.1}), or a combination (e.g. {0.1,0.1},{256,256}). |
