| 17 | * Defines the synta x of a URN used to i dentify VA images to the outsi de world. | |
| 18 | * An Imag eURN is de fined to b e in the f ollowing f ormat: | |
| 19 | * "urn" + ":" + "va image" + " :" + <site -id> + "-" + <assign ed-id> + " -" + <stud yId> + "-" + <patien tId> [+ "- " + <modal ity>] | |
| 20 | * where: | |
| 21 | * <site -id> is ei ther the s ite from w hich the i mage origi nated or t he string "va-imagin g" | |
| 22 | * <assi gned-id> i s the perm anent, imm utable ID as assigne d by the o riginating site or a | |
| 23 | * VA-do main uniqu e ID (an I maging GUI D). | |
| 24 | * <stud yId> is th e study IE N in VistA | |
| 25 | * <imag eIcn> is t he unique VA identif ier for th e patient | |
| 26 | * <moda lity> is t he modalit y of the i mage | |
| 27 | * | |
| 28 | * notes: | |
| 29 | * Exter nally, the site-id s hould not be interpr eted as a location c omponent. It should be | |
| 30 | * inter preted as no more th an a speci fier in a GUID (i.e. just a co mponent th at restric ts | |
| 31 | * the r equired do main of un iqueness). Initiall y and inte rnally to the VA onl y, it may | |
| 32 | * be us ed as a lo cation hin t. Extern al code th at relies on the sit e ID as a location | |
| 33 | * may c ease funct ioning wit hout warni ng. | |
| 34 | * | |
| 35 | * Image URN follow s the synt ax of a UR N as defin ed in W3C RFC2141 wi th the fol lowing add itional | |
| 36 | * rules on the na mespace sp ecific str ing: | |
| 37 | * The c haracter ' -' is a re served cha racter, us ed to deli mit portio ns of the namespace | |
| 38 | * speci fic string . Specifi cally it i s used to delimit th e originat ing site I D from the | |
| 39 | * site- assigned i mage ID. | |
| 40 | * The n amespace s pecific st ring must consist of uppercase , lowercas e and nume ric charac ters | |
| 41 | * with a '-' some where in t he middle. | |
| 42 | * | |
| 43 | * @see http://www .ietf.org/ rfc/rfc214 1.txt | |
