Besides their binary data file attachments on content documents have the following metadata fields:
| Name | Data type | Contents |
|---|---|---|
| created | Date | The creation time of the derivate |
| displayHeight | String | For images this returns the height of the displayed image in pixels, -1 for non-images |
| displayWidth | Integer | For images this returns the width of the displayed image in pixels, -1 for non-images |
| lastmodified | String | The last time this derivate was modified |
| md5Checksum | String | The MD5 checksum of this file attachments data. This is a hexadecimal string 32 characters long. |
| mimeType | String | The media type of this file derivate data |
| name | String | The file name of this file attachment, just like a file in a regular file system. |
| sha512Checksum | String | The SHA512 checksum of this file attachments data. This is a hexadecimal string 128 characters long. |
| size | Integer | The size of the attachment data in bytes |
Besides this metadata each file derivate may have custom fields, which are key/value pairs just like items. By this any OpenWGA functionality like file annotators or derivate creators may add custom metadata to every derivate.
