### LotusWriter Attributes

Attribute | Req | Description | Possible values
--- | --- | --- | ---
Basic
Domino connection |  | ID of the connection to the Lotus Domino database. |
Mode |  | Write mode. Insert mode always creates new documents in the database. Update mode requires view to be specified. Update operation first finds all documents in the view with same key values as incoming data record. After that either all found documents are updated, or only the first one is updated. | "insert" (default) | "update"
View |  | The name of the View in Lotus database within which the data records will be updated. |
Advanced
Mapping |  | When no mapping is provided, new documents will get the exact same set of fields as retrieved from the input port. With mapping, it is possible to customize which fields will be written to Lotus documents. Fields can be written with different names and order, some can be skipped and some written multiple times with different names. Often it is desirable to work with fields from the Document Lotus form. Mapping of input port fields onto Document form fields can be established in this attribute. | docFieldX := inFieldY; ...
Compute with form |  | When enabled, computation will be launched on the newly created document. The computation is typically defined in a Document form. This form is used by the users of Lotus Notes to create new documents. The computation may for example fill-in empty fields with default values or perform data conversions. | true (default) | false
Skip invalid documents |  | When enabled, documents marked by Lotus as invalid will not be saved into the Lotus database. This setting requires Compute with form attribute to be enabled, otherwise validation will not be performed. Validation is performed by the computing Document form action. | true | false (default)
Update mode |  | Toggles the usage of lazy update mode and behavior when multiple documents are found for update. Lazy update mode only updates the document when values get actually changed - written value (after optional computation) is different from the original value. When multiple documents are found to be updated, either only first one can be updated, or all of them can be updated. | "Lazy, first match" (default) | "Lazy, all matches" | "Eager, first match" | "Eager, all matches"
Multi-value fields |  | Denotes input fields which should be treated as multi-value fields. Multi-value field will be split into multiple strings by using the separator specified in the Multi-value separator attribute. The resulting array of values will then be stored as a multi-value vector into the Lotus database. | semi-colon separated list of input fields
Multi-value separator |  | A string that will be used to separate values from multi-value Lotus fields. | ";" (default) | "," | ":" | "|" | "\t" | other character or string

### Details

LotusWriter is a component which can write data records to Lotus databases. The writing is be done by connecting to a Lotus Domino server.

The data records are written to Lotus database as Documents. A document in Lotus is a list of key-value pairs. Every field of written data record will produce one key-value pair, where key will be given by the field name and value by the value of the field.

The user of this component needs to provide a Java library for connecting to Lotus. The library can be found in the installation of Lotus Notes or Lotus Domino. LotusWriter component is not able to communicate with Lotus unless the path to this library is provided or the library is placed on the user's classpath. The path to the library can be specified in the details of Lotus connection (see Lotus Connections).
