Introduction

GS1 Code Parser is a utility to deal with GS1 codes (e.g. GS1 Application Identifier, Hex-encoded RFID tag)

Written in Java

Method

AICodeParser Class

public String fillChecksum(String code,int gcpLength): Fill checksum digit of GS1 AI and Element String

e.g. (01)8061414112345* + 7 gcpLength --> (01)80614141123458

SSCC, GTIN, GDTI, SGCN, SGLN, GRAI, GSRNP, GSRN supported

public HashMap<String, String> parse(String code, int gcpLength): Parse sequence of multiple GS1 AI and Element String

e.g. (01)80614141123458(21)6789(10)4222(414)0614141123452(254)333 + 7 gcpLength -->

Then, HashMap contains

sgtin = urn:epc:id :sgtin:0614141.812345.6789

lgtin = urn:epc:class:lgtin:0614141.812345.4222

gtin = urn:epc:id pat:sgtin:0614141.812345.*

sgln = urn:epc:id :sgln:0614141.12345.333

SSCC, GTIN, SGTIN, LGTIN, GDTI, SGCN, SGLN, GRAI, GIAI, CPI, GSRNP, GSRN, ai:11, ai:13, ai:30, ai:310n, ai:390n supported

public void testSgtinAndLgtinAndSgln() {
		AICodeParser codeParser = new AICodeParser();
		String slgtin = "(01)80614141123458(21)6789(10)4222(414)0614141123452(254)333";
		int gcpLength = 7;
		HashMap<String, String> collection = codeParser.parse(slgtin, gcpLength);
		System.out.println("[TEST]" + slgtin + " includes " + collection.get("sgtin"));
		assertTrue(collection.get("sgtin").equals("urn:epc:id:sgtin:0614141.812345.6789"));
		System.out.println("[TEST]" + slgtin + " includes " + collection.get("lgtin"));
		assertTrue(collection.get("lgtin").equals("urn:epc:class:lgtin:0614141.812345.4222"));
		System.out.println("[TEST]" + slgtin + " includes " + collection.get("sgln"));
		assertTrue(collection.get("sgln").equals("urn:epc:id:sgln:0614141.12345.333"));
}

Electronic Product Code Information Service (EPCIS) enables to capture and share EPC-based event

( Basically RFID Tag event ). With EPCIS, event producer (e.g. RFID middleware) generates and sends events complying with EPCIS Document XML schema into EPCIS Repository. Then, these events can be globally shared with given queries
