<h1 class="main-heading">Importing CSV</h1>

Senfi allows you to create Assets by importing necessary information from a CSV file. The following section will detail the process to do so, and the specifications of the CSV file.

Prerequisite knowledge:
* Senfi concepts related to Asset
* Senfi concepts related to Lift & Movable Asset
* Senfi concepts related to Asset Relationship
* Zone & Level Zone concepts
* Measurement concepts, and corresponding Tag system.
* External event sources, and corresponding Tag system.

== How to Import CSV ==
[[File:CSV_Import_Steps1-5.png|thumb|center|700px|Steps 1 to 5 to import assets into Senfi via CSV|link=]]
# Go to "Import" tab
# Select "CSV" tab
# Select "IMPORT" tab
# Choose the .CSV file to be uploaded.
# Click "NEXT" [[File:CSV_Import_Steps6.png|thumb|center|700px|Preview of assets to be imported into Senfi via CSV Schema|link=]]
# Verify the information of the assets to be imported. Ensure all information is correct before proceeding with the actual import. 
## You can click on each asset row to view more information for individual asset.
## You can click on "BACK" to return to previous page if there is any information you wish to change.
## If there is an error with an asset, an [[File:Alert_icon.png|35px|link=]] alert will appear beside the asset information.
# Once all information is verified to be correct, click "IMPORT" to finish importing the CSV.
# If there is an error still remained when you click "IMPORT", the warning message will display and the assets with an error will be ignored if ignored the warning message.

== CSV File Specifications ==
The supported CSV format is RFC 4180, UTF-8. Saving as CSV from Excel should be compatible for most Excel versions. For the purposes of this guide, we will be using Excel as the CSV editor.

The imported CSV is split into 2 parts.
* Header
* Rows

The first row of the CSV file is the header row. The header row identifies the data contained within each column. The value of the header cell tells Senfi what to do with the column's data. For example, a column with header "Name" tells Senfi to assign the value of that column to the Name of each Asset.

The value of each header cell must equal to senfi-defined values, or conform to senfi-defined format, which will be outlined in the Headers section below. 
Any columns with non-conforming headers will be ignored.

Each subsequent row (2nd row onwards) in the CSV file is an Asset to be imported. 

=== Headers ===
==== Required Columns ====
The following headers must be in every imported CSV file, with valid values provided for each row. They are required to create an Asset.
* Name
* Is Virtual
* Site ID

==== Optional Columns ====
The following headers are optional. They provide more information about the Assets to be imported.
* Asset ID
** Required for updating the existing Asset
* Description
* Location X
* Location Y
* Location Z
* Is Movable
* Is Lift
* Zones
** a comma separated list of "Zone ID"s that the asset at.

==== Lift related Columns ====
If there are Lift assets, the following headers must exist to provide lift related information.
* Stops
** a comma separated list of "Level ID"s that the lift stops at. 
** E.g: [1b0dd17a-2785-4771-88ce-7158e7081d05,68caa9f0-32ed-44d1-94cc-9ddc768314d8]

==== Attribute Columns ====
To import Attribute information, add a header for each attribute, using the following format:
* [Attribute] <attribute_name>

If an Asset does not have an attribute, leave the column blank for that row.

==== Measurement Columns ====
To import measurement's tag information, add a header for each measurement's tag_field with the following format:
* [Measurement] <measurement_code>.<tag_field>
If an Asset does not have the measurement, leave the column blank for that row.

==== Event Columns ====
To import event's tag information, add a header for each event's tag_field with the following format:
* [Event] <event_def_id>.<tag_field>
If an Asset does not have the event, leave the column blank for that row.

==== Relationship Columns ====
To import asset relationship, add a header for each relationship type (hasPart|controls|feeds|serves|monitors) with the following format:
* [Relationship] <type>
If an Asset does not have this relationship type, leave the column blank for that row.
The column value is a comma separated list of "Asset ID"s that the asset have the relationship with.

==== Stream Columns ====
To add Video Streams to imported Asset, add the following header.
* Stream
The header can appear multiple times in the header row, as many as is required.

==== Iframe Columns ====
To add Iframe to imported Asset, add the following header.
* Iframe
The header can appear multiple times in the header row, as many as is required.
