Service overview
Two different subscriptions are related to Starter Kit service:
- Starter Kit feasibility check;
- Starter Kit.
The first one provides a service to validate customer requirements, the second uses the validated requirements to set up a knowledge base.
Starter Kit feasibility check
This subscription is free. A preliminary license check on all datasets is included into requirement analysis.
Provisioning process
The subscriber will receive an email with a link to a form to be filled with up to three
datasets and up to three
data questions. The subscriber has one week of time to answer the questionnaire.
During provisioning, the subscriber may be contacted by our staff that will evaluate the feasibility of requirements.The provisioning process will complete few days after the requirements availability.
If the LinkedData.Center staff thinks to be able to fulfill the subscriber expectations, a validated requirement ID is released and the customer is entitled to request the starter kit with the full Money Back Guarantee.
Subscription duration
The process should complete in one week.
Provided features
- knowledge base feasibility report;
- datasets license check;
- premium ticket support;
- a validated requirement ID (if requirements approved).
Service retirement
Feasibility report will be valid for one month after the service expiration.
Starter Kit
The starter kit subscription populates a knowledge base compliant with the subscriber requirements. It produces the needed data gateways, the formal description of the knowledge base, and the required ontologies.
This service is covered by Money Back Guarantee if the subscriber provides a validated requirement ID.
The provisioning process starts from the knowledge base requirements validated by the Starter Kit requirement validation service.
In the subscription form, it is possible to specify a knowledge base to use for a test. If not provided, we will create a temporary knowledge base for testing purposes.
Our data scientists will work to convert requirements into smart data. Depending on the complexity of the data and queries, this step will complete in one or two weeks. During provisioning, the subscriber may be contacted by our staff.
If the test knowledge base is not provided in the subscription form, a temporary knowledge base storage will be activated and it will contain the knowledge configuration:
- the formal RDF ontology (OWL–DL) required to add the semantic to your data and questions;
- a formal description of your knowledge base according to KEES (Knowledge Exchange Engine Schema) language profile. This description will alsobcontains the SPARQL queries needed to answer your questions;
- a graph of smart data derived from the required datasets.
The subscriber will receive a short document that contains:
- one URL you will use to populate/update the knowledge base;
- the URL of a private SPARQL endpoint with access credential (if test knowledge base not provided);
- three URLs you can use to import the answers to your questions as csv in your existing systems. The format of CSV will be compliant to this standard.
The service includes one month of premium ticket support.
The subscription has a duration of one month. The subscription duration can be extended by explicit written agreement between the subscriber and LinkedData.Center.
On subscription expiration any created test resource (e.g. temporary knowledge base storage) will be discarded.
Knowledge base storage requirements
The following requirements apply only if a test knowledge base is provided.
The provided test knowledge base storage must be big enough to store all data in the provided datasets after the translation into RDF triples. The storage index space can't exceed the one provided by your storage plan.
The test knowledge base is supposed to empty.
Dataset size limits
In our standard Starter Kit offering we put some limits on datasets size to keep the ontology design simple and to allow us a fixed price schema:
- on tabular data: no more than 20 columns and no more of 250.000 rows for each URL.
- on object collections: no more than one hierarchy level, no more than 20 different data type items;
- on linked data: SPARQL query must complete in max 60 sec;
- on all kinds of data: no more than 100 MB of uncompressed data for all dataset (cumulative of all slices).
If some big data tha exceed these limit are computed as multiiple dataset (i.e. a big table of 500.000 rows and 20 cols is computed as 2 distinct datasets) .
No answers can exceed the maximum time allowed for a SPARQL query. The answer fields are limited to 20 items.
This guarantee applies only to the subscribers who validated their requirements before subscribing to this service (i.e. an official ID provided with the subscription form).
If you are dissatisfied with our service for any reason, before service expiration, you can receive a full refund if you do the following:
Our support staff will review your request and issue a refund.
Note: this money-back guarantee applies only to our work, i.e.:
- ontology creation;
- data gateways;
- queries construction.
We do not accept refund requests based on the quality of data contained in data sources or on wrong questions.
