Migrating from outside Sharetribe ecosystem

How to import data from outside Sharetribe ecosystem

Table of Contents

Data from an existing marketplace can be migrated to Sharetribe Flex. If your marketplace is running in Sharetribe Go, there is a ready migration path that will be handled by us. We will handle the migration in this case and you can find the outline for this process here.

If you are running a marketplace outside the Sharetribe ecosystem, and would like to import data to Flex, it is possible. You will need to extract your data from its existing storage and transform it into Sharetribe's proprietary data format called Intermediary. Sharetribe will then validate the transformed data and load it into Flex.

This article will outline how you can encode data into Intermediary format, give you syntax examples of the format, and provide instructions on the migration process.

When to request a migration?

You should request a migration when:

  • You have a marketplace operating outside the Sharetribe ecosystem
  • You know you want to transfer your marketplace users and listings to your Flex marketplace. If you’d prefer to re-start your community in Flex, then a migration is not needed.
  • You have started developing with Flex

You will work with Sharetribe’s engineers to complete your migration. If you're planning to migrate your data to Flex, you should always start the process with a test migration to your dev environment, and ensure everything looks correct there, before doing a live migration. If you want to initiate the (test or live) migration process, you should email flex-support@sharetribe.com with the subject “Migrating from outside Sharetribe”. Please include your Flex organization (your organization is displayed in your Console in the top right corner).

Intermediary data

Intermediary is an edn (https://github.com/edn-format/edn) data format that allows defining data rows for marketplaces. It supports creating links between rows via references.

We recommend that you use an edn library to generate the data and validate the .edn syntax to ensure that the file is up to standard.

edn libraries exist for multiple languages, for example JavaSript, Python, and Ruby. Clojure has built-in support for edn. Usually these libraries support encoding data structures to edn and creating custom tagged elements.

Here's an example of how to write a bit of intermediary data in edn format using JavaScript libraries jsedn and uuid to represent a user and a listing:

const edn = require('jsedn');
const { v4: uuidv4 } = require('uuid');

const tagged = (tag, value) => new edn.Tagged(new edn.Tag(tag), value);
const uuid = () => tagged("uuid", uuidv4());
const price = (amount, currency) => tagged("im/money", [amount, currency]);

const email = data => {
  const { emailAddress } = data;
  return new edn.Map([edn.kw(":im.email/address"), emailAddress,
                      edn.kw(":im.email/verified"), true]);
};

const profile = data => {
  const { firstName, lastName } = data;
  return new edn.Map([edn.kw(":im.userProfile/firstName"), firstName,
                      edn.kw(":im.userProfile/lastName"), lastName]);
};

const user = data => {
  const { alias, emailAddress, firstName, lastName } = data;
  const role = new edn.Vector([edn.kw(":user.role/customer"), edn.kw(":user.role/provider")]);

  return new edn.Vector([new edn.Vector([edn.kw(":im.user/id"), uuid(), alias]),
                         new edn.Map([
                           edn.kw(":im.user/primaryEmail"), email(data),
                           edn.kw(":im.user/createdAt"), tagged("inst", new Date().toISOString()),
                           edn.kw(":im.user/role"), role,
                           edn.kw(":im.user/profile"), profile(data)
                         ])
                        ]);
};

const listing = data => {
  const { alias, title, priceAmount, author } = data;
  return new edn.Vector([new edn.Vector([edn.kw(":im.listing/id"), uuid(), alias]),
                         new edn.Map([
                           edn.kw(":im.listing/title"), title,
                           edn.kw(":im.listing/createdAt"), tagged("inst", new Date().toISOString()),
                           edn.kw(":im.listing/state"), edn.kw(":listing.state/published"),
                           edn.kw(":im.listing/price"), price(priceAmount, "EUR"),
                           edn.kw(":im.listing/author"), tagged("im/ref", author)
                         ])
                        ]);

const userAlias = edn.kw(":user/john");
const e = new edn.Map([edn.kw(":ident"), edn.kw(":mymarketplace"),
                       edn.kw(":data"), new edn.Vector([
                         listing({
                           alias: edn.kw(":listing/rock-sauna"),
                           title: "A solid rock sauna",
                           priceAmount: 12.20,
                           author: userAlias}),
                         user({
                           alias: userAlias,
                           emailAddress: "foo@sharetribe.com",
                           firstName: "John",
                           lastName: "Doe"
                         })
                       ])
                      ]);

console.log(edn.encode(e)); // or save to file

Format

Intermediary is specified as a map with the following keys:

  • :ident - identifies the target marketplace by marketplace ID,
  • :data - a seq of marketplace data rows. Each row is a 2-tuple (an array with two elements) of id and content.

You can find your marketplace ID in Flex Console > Build > General. Note that the anonymised test file needs to specify your dev environment marketplace ID and your live data file needs to specify your live environment marketplace ID.

The id part of the data row 2-tuple is specified as a tuple of 1 to 3 elements. The first element is always an id attribute and identifies the row type. The second element can be an alias or an import id. A 3 element version has id attr, import id and an alias.

;; 1 element tuple
[:im.stripeAccount/id]

;; 2 element tuple with import id
[:im.image/id #uuid "58afd8e1-e336-4ca4-a1e7-ff1d91856a6c"]

;; 2 element tuple with alias
[:im.user/id :user/jane]

;; 3 element tuple
[:im.listing/id #uuid "b074e697-ab0c-4746-a195-c58d73606b1f" :listing/rock-sauna]

Import ids can be given to rows and they should be unique for the marketplace and have type UUID. Aliases can be used to reference rows from other rows. Aliases are useful when the data is written by hand. Import ids are useful for programmatically generated / exported data.

Note that import ids are only used in the import phase and they can not be mapped to existing resource ids, because the final resource id is not created based on the import id. In other words, if e.g. your dev marketplace already has data rows, you cannot reference those rows by import ids in the Intermediary file.

If you are not generating data by hand, it is recommended that you use the 2 element form of the id tuple. This means using unique UUIDs throughout the file to reference entities. You can read more about generating UUIDs for your data here.

Aliases

If you currently use non-UUID ids in your data, you can also use them to generate aliases for the data. Aliases must be unique across the file, and they cannot contain spaces.

Since aliases are namespaced keywords (e.g. :user/jane in the example), the unique part cannot begin with a number. If your unique ids begin with a number, you can generate the aliases for instance in the following pattern:

// type: 'user', id: 123
alias = (type, id) =>
// returns ':user/u123'
return ':{type}/{type1stletter}{id}'

Referencing

When you have data that is dependent on each other, such as listings related to users and reviews related to listings, you can reference the data within the import file. You can refer to resources by either alias or UUID with the #im/ref tagged element. The supported references for each type, if any, are listed in the type description in the Supported types section below. Note that referencing data with an id or alias that does not exist in the same file causes a validation error.

;; Referencing a listing by alias
[[:im.image/id #uuid "58afd8e1-e336-4ca4-a1e7-ff1d91856a6c"]
  #:im.image{:url "https://asset-url.someservice.com/path/to/img1.jpg"
            :sortOrder 1
            :listing #im/ref :listing/rock-sauna}]

;; Referencing a listing by UUID
[[:im.image/id]
  #:im.image{:url "https://asset-url.someservice.com/path/to/img2.jpg"
            :sortOrder 2
            :listing #im/ref [:im.listing/id #uuid "b074e697-ab0c-4746-a195-c58d73606b1f"]}]

See the example for more details.

Supported types

Currently, the Intermediary format supports the following top level types:

- :im.user/id
- :im.listing/id
- :im.image/id
- :im.stripeAccount/id
- :im.review/id

This means that the Intermediary supports importing:

The migration process has some built-in validation for the types within an Intermediary file. Optional keys must have non-empty values, and if an optional key does not have a value, the key must be omitted for that resource. Empty strings are validated as empty values.

For listings, users, and reviews, the corresponding Flex API resource reference is linked under their type description. It is good to note that the shape of the Intermediary data corresponds to the API reference, however there may be differences in e.g. attribute naming.

                      :description "A very nice solid rock sauna built solely of wood.\nHere's some more sensible stuff."
                      :state :listing.state/pendingApproval
                      :location #im/location [23.12 21.21]
                      :price #im/money [12.12M "EUR"]
                      :currentStock 5
                      :publicData {:category "rock"
                                   :amenities ["sauna" "pool"]}
                      :author #im/ref :user/john}]

User

Supported fields to migrate: API reference current user resource.

Inside the user resource, the email resource differs a bit from the documentation. The email resource is referenced under :primaryEmail key like this:

:primaryEmail {:im.email/address "foo@sharetribe.com"
               :im.email/verified true}

The Intermediary file validation also checks that the email address format is valid.

At the moment, all users created within Flex are defined with both :user.role/customer and :user.role/provider. The user roles cannot be configured after the import, so we recommend that you add both roles for all users and determine any distinction between user groups in your client application.

Required attributes for :im.user

  • :im.user/primaryEmail
    • :im.email/address (validated email string)
    • :im.email/verified (boolean)
  • :im.user/role (array)

  • :im.userProfile/protectedData (JSON)
  • :im.userProfile/privateData (JSON)
  • :im.userProfile/metadata (JSON)
  • :im.userProfile/avatar (#im/ref)

Supported references

  • #im.userProfile/avatar -> #im.image

Example syntax

[[:im.user/id :user/john]
  #:im.user{:createdAt #inst "2018-04-17T06:55:04.291-00:00"
            :primaryEmail {:im.email/address "foo@sharetribe.com"
                          :im.email/verified true}
            :profile {:im.userProfile/firstName "John"
                      :im.userProfile/lastName "Doe"
                      :im.userProfile/displayName "John D"
                      :im.userProfile/bio "He's just a poor boy from a poor family.\nSpare him his life from this monstrosity."
                      :im.userProfile/publicData { :premiumAccount true }
                      :im.userProfile/avatar #im/ref :avatar/john}

Optional attributes - only include the key if it has a non-empty value

  • :im.image/listing (#im/ref)
  • :im.image/sortOrder (integer)

Supported references

  • #im.image/listing -> #im.listing

Note that for profile images, the reference is added in user with #im.userProfile/avatar -> #im.image

Example syntax

[[:im.image/id #uuid "58afd8e1-e336-4ca4-a1e7-ff1d91856a6c"]
  #:im.image{:url "https://asset-url.someservice.com/path/to/img1.jpg"
            :sortOrder 1
            :listing #im/ref :listing/rock-sauna}]

Stripe account

Required attributes

  • :im.stripeAccount/stripeAccountId (string)
  • :im.stripeAccount/user(#im/ref)

Example syntax

[[:im.stripeAccount/id]
  #:im.stripeAccount{:stripeAccountId "a_stripe_id"
                    :user #im/ref :user/john}]

Review

Supported fields to migrate: API reference review resource

              :rating 5
              :type :review.type/ofProvider
              :state :review.state/public
              :createdAt #inst "2018-01-06T00:10:10Z"
              :author #im/ref :user/jane
              :subject #im/ref :user/john
              :listing #im/ref :listing/rock-sauna}]

Value types

Intermediary format uses some notable value types:

Location

Location is an Intermediary-specific type specified as a 2-tuple of latitude and longitude. Both latitude and longitude are 32 bit floats. The location attribute is used in the Sharetribe Web Template to provide listing location coordinates through either Mapbox or Google maps.

If your source data has addresses specified, and you would like to use them to determine coordinate information, you can use a 3rd party geocoding api such as Mapbox or Google in your data transformation setup. We recommend that you provide a valid location attribute if your marketplace uses maps in some way, whether or not you provide an address attribute in e.g. public data.

#:im.listing{...
            :location #im/location [23.12 21.21]
                      ...}

Money

Money is an Intermediary-specific type and it is defined as [ amount, currency ]. Note that in the Flex API reference for listings, the money type differs somewhat from the Intermediary #im/money type – the #im/money type uses decimals for the amount whereas the API money type amount is given as an integer representing the currency's minor unit.

#:im.listing{...
            :price #im/money [12.12M "EUR"]
            ...}

UUID

A Universally Unique identifier (UUID) can be used to identify resources within the migration file using .edn's built-in #uuid tagged element. If your data already uses UUIDs, make sure their format matches the canonical representation.

:im.image/id #uuid "58afd8e1-e336-4ca4-a1e7-ff1d91856a6c"

Timestamp

Timestamp in .edn is given as an #inst tagged element.

:createdAt #inst "2018-04-17T06:55:04.291-00:00"

Things to consider

No updates are supported

The import is loaded only once to the live environment and currently updates with multiple live data imports are not supported.

Test import

We can perform multiple imports to the dev environment, with the caveat that no data deletion in this situation is possible. This might lead to duplicate information being uploaded to the dev environment.

Also, anonymizing test import data by hiding sensitive information like names, addresses, email addresses and Stripe keys is highly recommended.

We recommend that you only use a subset of your data for the test import. The purpose of the test migration is to confirm that your extract-and-transform process creates a migration file that is valid and consistent, so there is rarely need for importing the anonymized equivalent of your full user data into the dev environment.

Password management

Importing passwords from outside the Sharetribe ecosystem is not supported. This means that your users will be logged out of the service and are required to use the recover password functionality to gain access.

Security and sharing data

Since you will be sharing user information about your service to ours, it is essential to share the data securely. Contact us when you are ready to share the data.

Anonymised test data for validation and test migrations can be shared via email. However, for live data with real user information, we will create a secure upload link that is valid for an agreed amount of time.
