Data Interoperability and FAIRness Through Existing Web Technologies

DTL Partner WkshpNovember, 2016

Page 2: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

The Problem...one recent survey of 18 microarray studies found that only two were fully reproducible using the archived data. Another study of 19 papers in population genetics found that 30% of

analyses could not be reproduced from the archived data and that 35% of datasets were incorrectly or insufficiently

described.

Page 3: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

The ProblemWe surveyed 100 datasets associated with nonmolecular studies in journals that commonly publish ecological and

evolutionary research and have a strong PDA policy. Out of these datasets, 56% were incomplete, and

64% were archived in a way that partially or entirely prevented reuse.

FAIR

Findable→ Globally unique, resolvable, and persistent identifiers→ Machine-actionable contextual information supporting discovery

Accessible→ Clearly-defined access protocol→ Clearly-defined rules for authorization/authentication

Interoperable→ Use shared vocabularies and/or ontologies→ Syntactically and semantically machine-accessible format

Reusable→ Be compliant with the F, A, and I Principles→ Contextual information, allowing proper interpretation→ Rich provenance information facilitating accurate citation

The Four Principles

There was very little disagreement

about F, about A,

or about R

Keeping the history brief

A series of teleconferences led to the concept of putting metadata into an iterative set of ~identical “containers”

Page 17: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Skunkworks HackathonsThe “containers of containers of containers” idea was elaborated by the belief that we should also

reject any solution that required a new API

ProgrammableWeb.com already catalogues >16,000 different Web APIs!!!!!!

Hypermedia-driven, NOT parameter-driven

The phrase “my REST API” makes almost no sense,and in bioinformatics, is usually accompanied by a page explaining the key/value pairs you should add to the URL to access various functions.

This Is Not REST!

I

Defines HTTP-resolvable URIs for each of these containers

Defines the concept of a “Container” - a machine-actionable way to represent repositories, data deposits, data files, data points, and their metadata

Uses a widely accepted standard (DCAT) to relate metadata to data → machine-actionable data mining

Page 25: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Caveats

We used LDP as “inspiration”

Some parts of LDP are not really “REST” (in our opinion) so we stripped-out

those parts in favour of a 100% API-free solution

For the moment we require a read-only solution;

LDP defines a read-write platformso we don’t use those portions either

(for now)

What can we describe with FAIR Accessors?

FAIR Accessors provide a machine-actionable, structured,

REST-oriented way to publish Metadata

about a wide range of scholarly “entities”

Page 28: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

What can we describe with FAIR Accessors?

Warehouses (e.g. EBI)

Databases (e.g. UniProt)

Repositories (e.g. Zenodo, Dataverse, Leiden Repository, etc.)

Datasets (e.g. output from a workflow)

Research Objects (data a/o workflow a/o results a/o publications)

Data “slices” (e.g. the result of a database query)

Data Records (e.g. image, excel file, patient clinical record)

What does a FAIR Accessor “look like”?

In REST, a “Resource” is “anything that can be identified”

whether that is a single thing or an identifiable collection of things,

and whether it exists in the real-worldor only in the network.

A “Resource” is identified by a URI

A real-world scenario...

Imagine you are publishing a paper describing the evolution of proteins

involved in the RNA Processing machineries of the fungus Aspergillus nidulans.

If you want to be a “good” scholarly publisher, interested in transparency and reproducibility,

what is the first thing you need to explain to your readers and reviewers?

Two ways to retrieve the record - RDF or HTML

(in REST-speak, two Representations of that Resource)

Page 83: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Note that this metadata record is somewhat more FAIR, than what you can (easily) retrieve from UniProt itself!

e.g. the UniProt record does not include the citation or license information - you have to manually surf around the UniProt Web page to find that.

So the Accessor makes UniProt’s already notably FAIR data, even more FAIR (with respect to “R”)

Page 84: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

How FAIR are we now?What does the Accessor give us?

Page 85: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

What we have achieved

We have created a FAIR record for something - i.e. a slice of a database - that was, historically, un-recordable and un-identifiable in any formal way.F

F + A

F + RAccessors are a standard approach to providing human & machine accessible metadata to facilitate appropriate discovery (contextual, biological), proper usage (license) and proper citation for any kind of data.

The discovery, accessibility, and drill-down/up behaviors do not require any novel API, rather simply rely on global Web standards; this allows them to be indexed by existing Web search engines

Page 86: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

What we have achieved

F + AI The metadata itself uses machine-accessible syntaxes, and widely adopted ontologies and vocabularies, thus easily integrates with other metadata

A Accessors provide a lightweight means to protect privacy while still providing the maximum degree of transparency possible

+ Accessors can be static, or dynamic. i.e. we can provide template Accessor file(s) that are edited in Notepad, then published together with the data; or Accessors can dynamically generate their output from code (e.g. layered on a database server)

Page 87: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Can we be FAIRer?

Page 88: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Not good enough for the Skunk!

So far we have only addressed Interoperability and FAIRness of Metadata

The Holy Grail of Interoperability is to provide interoperable Data.

Page 89: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

FAIR Projection:

Providing FAIR Datafrom non-FAIR Data

Page 90: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

This is going to be a bit complicated, but please be patient

Interoperability is Hard!!

Page 91: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Imagine the data we need to integrate

is in a CSV fileIn FigShare or Zenodo

How do we discover and integrate that data?

CSV (usually) has no inherent semanticsand semantics is ~impossible to automatically guess

Page 92: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Things we need to do:

We need a way to query “opaque” data blobs (like CSV) about their content

We need a way to retrieve that content in a FAIR format

We need, therefore, to model semantics for that opaque data content

We need to model various semantics for that content (one “size” doesn’t fit all!)

We need to associate those semantic models with a record or record-sets

We need a way to query those semantics determine which “size” fits our req’s

We would like to reuse semantic definitions as much as possible

We need to do all of this without creating a new API :-)

Triple Pattern Fragments (TPF)A REST interface for requesting/retrieving RDF Triples

(from any source)

Ruben Verborgh

“Slices” of data, from any source, are considered Resources and are therefore represented by a distinct URL:

http://some.database.org/dataset?s=___;p=___;o=___

Calling HTTP GET on a TPF URL returns the set of Triples matching {?s, ?p, ?o}PLUS hypermedia instructions and Resource URLs for other relevant slices.

Triple Pattern Fragments (TPF)A REST interface for retrieving RDF Triples

Ruben Verborgh

For example, the “BMI” column from a patient registry is a Resource with the URL:

http://my.registry.org/patients?p=CMO:0000105 (CMO:0000105 = “body mass index””)

HTTP GET gives me all BMI triples in the registry, together with other Resource URLs representing other “slices” that might be useful, for example:

http://my.registry.org/patients?p=CMO:0000004 (CMO:0000004 = “systolic B.P.”)

http://my.registry.org/patients?p=CMO:0000105 (CMO:0000105 = “body mass index””)

HTTP GET gives me all BMI triples in the registry, together with other Resource URLs representing other “slices” that might be useful, for example:

http://my.registry.org/patients?p=CMO:0000004 (CMO:0000004 = “systolic B.P.”)

Page 97: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

We have a standard, RESTful way to request triples from any data source

i.e. every slice of every dataset will be considered a distinct Resource→ simply call HTTP GET on that Resource to get the Triples

Page 98: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

But it’s a disaster! We have no way to know what Resources are

available for any given dataset or what those Resources “are”

(proteins? genes? patients? articles?)

...and still no defined way to generate the associated Triples

RMLA way to describe the structure of an RDF document

Anastasia Dimou

RML allows us to create models of (meta)data structures

“What could this (meta)data look like?”

RML fulfills similar objectives to DCAT Profiles, the Dublin Core Application Profile, and ISO 11179 - Metadata Registries;

but has added advantages!

Page 115: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Page 116: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Sadly, there is no magic wand to create interoperability

Someone has to write the TPF server, and host it somewhere

Interoperability will never come “for free”

(because semantics will never come “for free”)

Page 117: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

However, there are reasons for optimism!

1. People must transform data anyway in order to integrate it - this is a daily routine in most bioinformatics labs

2. For the most common file formats (e.g. CSV or Excel), there are RML-based tools to automate these transformations; simply create an RML model of what you want/need, and point the tool at the file.

3. Investing time into creating an RML model, vs. ad hoc “re-useless” transformation, makes it ~trivial to create a TPF server, and therefore to create a FAIR Projector for your own data transformation needs… and it is reusable!

AND4. Because the RML of Triple Descriptors is itself so simple (one triple!), we can

also templatize their construction, making the entire process even more trivial

5. Citations Citations Citations! FAIR Accessors/Projectors are FAIR objects! You can get credit if other people use your Projector for their own analyses!

Page 118: FAIR Data Prototype - Interoperability and FAIRness through a novel combination of Web technologies

Summary of FAIR Projectors

FAIR Projectors create interoperable data, associated with interoperable metadata, that can be discovered by querying a FAIR Port (or potentially Google, when/if Google properly indexes RDF)

F+I+R

A + I

IFAIR Projectors can convert non-FAIR data into FAIR data, or can change the structure, URL format, or semantics of existing FAIR data sources

FAIR Projectors can be deployed over, and provide a common interface to:- Static Data Deposits (in any format!) - Databases- Triplestores- Certain (common) types of Web Services

R+++ Triple Descriptors are FAIR entities, intended for reuse, & None of this required a new API

Anyone can publish an Accessor for any publicly-visible data!

Every possible representation for Record R

Can be used simply for discovery of the “type” of content inside of Record R, or can be used to discover a FAIR Projector that executes the transformation
