Digital assets
Digital assets are files used in relation with the data being managed, such as images, audio files, video files, PDF documents, Microsoft Office documents, and other types of files. Any type of file can be uploaded as a digital asset.
Digital Asset Management (DAM)
The Digital Asset Manager (DAM) is the set of folders, repositories, and processes used to store digital assets and make them accessible to the rest of EnterWorks.
The records in the DamMaster repository hold the metadata for the digital assets.
Each digital asset has one record in DamMaster. The metadata
includes filepath, file extension, and any other metadata that can be extracted from
the image such as width and height.
Depending on system configuration, digital assets can be associated with any repository record.
A digital asset orphan is either:
-
A digital asset file that does not have a record in DamMaster.
-
A record in DamMaster that does not have a link to a digital asset file.
An image's Image Priority value specifies the order it is listed in a linked list and it identifies the image so it can be included in an export template. The Classic UI's export template editor allows you to select image priority values up to the limit specified in shared configuration properties. You can change this limit by editing the shared configuration property.
Variants
EnterWorks can create variants for the following image file formats. Other image file types might also be supported.
- EPS
- GIF
- JPEG
- JPG
- PNG
- TIFF
Resizing images is supported for all image types, however, more advanced operations are only supported for JPG, JPEG, PNG, and TIFF formats.
The records of the following repositories define the image variants that can be generated.
- DAMVariantSizes
- DamVariants
The record's attributes include values such as the dimensions of the variant, the image quality, whether to include a watermark, the text of the watermark, and compression quality. One of repository's attributes is Regex Rule. If it is set, it contains a regex pattern expression. If the image's filename matches the pattern specified in Regex Rule, the variant defined by the record is generated. For more information and examples, see Governing Image Variant Creation with Regex Rules.
When an image is uploaded:
- DAMVariantSizes records are checked to see if the image's filename matches any of the Regex Rules in the records. If a rule applies, the variant is generated. Multiple rules may apply.
- If none of the rules apply, the Regex Rules in the DAMVariants repository's records are checked. If a rule applies, the variant is generated.
- If no Regex Rules apply, the variant is generated according to each record in DAMVariants that has an empty Regex Rule attribute.
Image Processing Speed
Factors that affect how quickly images are uploaded and processed include:
- Client and server specifications: Image processing can be slowed by long responsive times between servers, poor client upload speed, server region, low disk space, and other environmental factors. Even antivirus systems can considerably slow down IO operations and impact image upload and processing speeds.
- Image operations and image complexity: Some advanced operations may take more resources, such as padding an image, removing a background, and filling a background. These operations may be performed even if they are not specified in the DamMaster repository. For example, changing the format of a TIF image with a transparent background to JPG requires manipulation of the image's background.
