Image

Image is the abstract base every imaged-document wrapper in the domain derives from (OP-DOM-20), providing the shared Id and IFN-URL-building behaviour needed to link back to the imaging system, plus the static translation between the imaging system's numeric document-set (ifnDs) codes and their human-readable production/development identifiers (DOM-BR-210).

Purpose

• Builds the IFN: display URL for a wrapped image by resolving its image system and mapping the system's ifnDs value to a readable identifier, returning an empty string when no image system is found.
• Translates known ifnDs values between their numeric form and their "387/4"/"388/2" string form (production and development document sets respectively), returning an empty/zero value for any unrecognized input (DOM-BR-210).

Context

• Namespace: SAIF.Domain.Model.Imaging
• Assembly/package: SAIF.Domain (packaged in SAIF.SAIFCode.Core)
• This is an abstract class; both constructors are protected and only usable by derived types, so it has no public constructors of its own.

Public members

Member	Signature	Purpose
Id	public long Id { get; }	The wrapped image's identifier.
IfnUrl	public string IfnUrl { get; }	The display string "IFN: {ifnDs}-{ifnId}" for the wrapped image's image system, or an empty string when the image has no associated image system.
ConvertIfnDs (long overload)	public static string ConvertIfnDs(long ifnDs)	Maps a numeric ifnDs value to its readable form ("387/4" for the production value, "388/2" for the development value); an empty string for any other value (DOM-BR-210).
ConvertIfnDs (string overload)	public static long ConvertIfnDs(string ifnDs)	Maps the readable form ("387/4" or "388/2") back to its numeric value; 0 for any other value (DOM-BR-210).

Inherited public members

Members in this section are inherited from DomainBase<TItem> in SAIF.Domain. They are available on this type through inheritance (via the intermediate DomainRepositoryBase<TItem> base).

Member	Signature	Purpose	Origin
HasData	public virtual bool HasData { get; }	Reports whether the wrapped image entity is present, evaluated as !DataItem.IsNull().	SAIF.Domain — DomainBase<TItem>

Behavioral notes

• A commented-out CreateImageAffiliation method remains in source, suggesting affiliation-creation support was planned or removed but never completed*.
• The protected GetAffilliatedImages method (note the source's non-standard "Affilliated" spelling, explicitly suppressed via CA1704) is available to derived types but is not part of this type's public surface.

Constraints and usage notes

• Because both constructors are protected, Image can only be instantiated through a concrete derived class; this page documents the base behaviour every such derived type inherits.
• ConvertIfnDs only recognizes the two hard-coded production/development document-set values; any other imaging environment's ifnDs value round-trips to an empty/zero result rather than throwing.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts.
