GS1 data can be encoded in a number of symbologies. Application Identifiers
(AIs) should be enclosed in `[square brackets]` followed by the data to be
encoded (see [6.1.10.3 GS1-128]). For matrix symbologies, GS1 Digital Link URIs
can also be given. To encode GS1 data use the `--gs1` option. Alternatively,
use the `--gs1strict` option, which strictly verifies the GS1 data.

#### 4.11.3.1 GS1 Data Entry
Those that encode an implicit AI take numeric data in their linear part without
any further markup - see respective descriptions in [6. Types of Symbology].
GS1-128, GS1 DataBar Expanded (including Expanded Stacked), the matrix
symbologies and the 2D component of GS1 Composite symbologies, all of which can
encode multiple AIs, require markup in the data to distinguish AIs.
The traditional way in Zint of specifying GS1 data for these cases is to delimit
the GS1 AIs in square brackets:
```bash
zint -b AZTEC -d "[01]09520123456788[10]BATCH4[21]07" --gs1
```
(Note that for the matrix symbologies the `--gs1` option must be given.)
Parentheses (round brackets) may be used instead by giving the `--gs1parens`
option:
```bash
zint -b AZTEC -d "(01)09520123456788(10)BATCH4(21)07" --gs1parens
```
If the data includes opening parentheses when using the latter format, they must
be escaped and the `--esc` option given:
```bash
zint -b AZTEC -d "(01)09520123456788(90)Var\(34)" --esc --gs1parens
```
Closing parentheses may also be escaped for clarity.
For matrix symbologies, a GS1 Digital Link URI may be used:
```bash
zint -b AZTEC -d "https://example.com/01/09520123456788/10/BATCH4/21/07" --gs1
```
A further way to specify GS1 input is "Unbracketed AI", a GS1 Syntax Engine
format[^10] that uses carets (`^`) to indicate any required `FNC1`s.[^11] The
data must start with a caret:
```bash
zint -b AZTEC -d "^010952012345678810BATCH4^2107" --gs1
```
[^10]: For more information on the "Unbracketed AI" format for GS1 data entry,
see the [GS1 Barcode Syntax Engine overview](
https://gs1.github.io/gs1-syntax-engine/).
[^11]: `FNC1`s are required to terminate the data of any AI (except when the
last) **apart** from those whose **first two digits** match the following: 00,
01, 02, 03, 11, 12, 13, 15, 16, 17, 20, 31, 32, 33, 34, 35, 36 and 41, as
specified in GS1 General Specifications 26.0 Table 7-6 "Element strings with
predefined length using GS1 Application Identifiers". Note that this applies
even to AIs with fixed lengths, so e.g. the data for AI 3940 must have a
terminating `FNC1` (except when the last AI).
The final way to specify input is the related "raw" mode using the `--gs1raw`
option. Here `FNC1`s are indicated by Group Separators (`GS`, ASCII 29, escape
sequence `\G`). It does not start with a `GS`:
```bash
zint -b AZTEC -d "010952012345678810BATCH4\G2107" --esc --gs1raw
```
#### 4.11.3.2 GS1 Options
Apart from `--gs1`, `--gs1parens` and `--gs1raw` discussed above, there are two
other GS1 options.
- `--gs1strict`, which enables the use the GS1 Syntax Engine to
strictly validate GS1 data, including GS1 Digital Link URIs (by default Zint
does not validate Digital Links at all). It requires that the `gs1encoders`
library was present when Zint was built, otherwise the default built-in
validation will be used.
- `--gs1nocheck`, for use with legacy systems that have data that does not
conform to the current GS1 standard. Printable ASCII input is still checked for,
as is the validity of GS1 data specified without AIs (e.g. linear data for GS1
DataBar Omnidirectional/Limited/etc.). Also checked is GS1 DataBar Expanded and
GS1 Composite input that is not in the GS1 encodable character set 82 (see GS1
General Specifications 26.0 Table 7-2 "GS1 AI encodable character set 82"),
otherwise encodation would fail. In "Unbracketed AI" and raw mode, overlong AI
data will also fail.
All the GS1 options imply `--gs1`.

4.11.3.1 GS1 Data Entry
Those that encode an implicit AI take numeric data in their linear part without
any further markup - see respective descriptions in 6. Types of Symbology.
GS1-128, GS1 DataBar Expanded (including Expanded Stacked), the matrix
symbologies and the 2D component of GS1 Composite symbologies, all of which can
encode multiple AIs, require markup in the data to distinguish AIs.
The traditional way in Zint of specifying GS1 data for these cases is to delimit
the GS1 AIs in square brackets:
zint -b AZTEC -d "[01]09520123456788[10]BATCH4[21]07" --gs1
(Note that for the matrix symbologies the --gs1 option must be given.)
Parentheses (round brackets) may be used instead by giving the --gs1parens
option:
zint -b AZTEC -d "(01)09520123456788(10)BATCH4(21)07" --gs1parens
If the data includes opening parentheses when using the latter format, they must
be escaped and the --esc option given:
zint -b AZTEC -d "(01)09520123456788(90)Var\(34)" --esc --gs1parens
Closing parentheses may also be escaped for clarity.
For matrix symbologies, a GS1 Digital Link URI may be used:
zint -b AZTEC -d "https://example.com/01/09520123456788/10/BATCH4/21/07" --g
s1
A further way to specify GS1 input is “Unbracketed AI”, a GS1 Syntax Engine
format[10] that uses carets (^) to indicate any required FNC1s.[11] The data
must start with a caret:
zint -b AZTEC -d "^010952012345678810BATCH4^2107" --gs1
The final way to specify input is the related “raw” mode using the --gs1raw
option. Here FNC1s are indicated by Group Separators (GS, ASCII 29, escape
sequence \G). It does not start with a GS:
zint -b AZTEC -d "010952012345678810BATCH4\G2107" --esc --gs1raw
4.11.3.2 GS1 Options
Apart from --gs1, --gs1parens and --gs1raw discussed above, there are two other
GS1 options.
- --gs1strict, which enables the use the GS1 Syntax Engine to strictly validate
GS1 data, including GS1 Digital Link URIs (by default Zint does not validate
Digital Links at all). It requires that the gs1encoders library was present
when Zint was built, otherwise the default built-in validation will be used.
- --gs1nocheck, for use with legacy systems that have data that does not conform
to the current GS1 standard. Printable ASCII input is still checked for, as is
the validity of GS1 data specified without AIs (e.g. linear data for GS1
DataBar Omnidirectional/Limited/etc.). Also checked is GS1 DataBar Expanded
and GS1 Composite input that is not in the GS1 encodable character set 82 (see
GS1 General Specifications 26.0 Table 7-2 “GS1 AI encodable character set
82”), otherwise encodation would fail. In “Unbracketed AI” and raw mode,
overlong AI data will also fail.
All the GS1 options imply --gs1.
