Video summary
This webinar from the Center for Open Science introduces Persistent Identifiers (PIDs) as essential tools for enhancing research visibility and data management on the OSF platform. PIDs are defined globally unique, persistent, interoperable, and machine-readable identifiers that ensure resources like people, organizations, and digital objects can be reliably located over time regardless of URL changes. The session explains how these identifiers disambiguate between entities with similar names, such as distinguishing one researcher from another, and serve as stable links to publications known as Uniform Resource Identifiers (URIs). Unlike standard URLs which may break or redirect unpredictably, PIDs are maintained by organizations committed to resolving them consistently, thereby ensuring long-term accessibility for research outputs.
The core benefit of using PIDs lies in their ability to construct an information graph rather than relying on isolated records. By linking identifiers such as ORCID for authors, ROR for institutions, and DOIs for publications or datasets, the OSF can infer complex relationships between researchers, organizations, and works automatically. This interconnected network allows users to answer sophisticated questions about research impact by aggregating data across multiple repositories without duplicating information manually. For instance, if a preprint receives a DOI registered with Crossref while being authored by someone linked via ORCID at an institution verified through ROR, the system can seamlessly associate all these elements into a cohesive profile that expands as new works are published or versions are updated.
To leverage this infrastructure effectively, researchers are encouraged to register for their own ORCID iDs and link them directly to their OSF accounts using single sign-on verification. Once connected, any DOI generated for preprints on the platform will automatically populate the researcher's profile without additional administrative effort. Furthermore, users can enrich project registrations by attaching DOIs or other PIDs to supplementary materials like code repositories, data sets, and published papers through a simple interface that displays colored icons upon successful linking. This practice not only reduces the burden of metadata entry but also ensures that research outputs are precisely identified for publishers and aggregators who rely on these standards for dissemination and citation tracking.
The webinar concludes by highlighting how PIDs have become a mandatory requirement in major funding policies, including those from the National Institutes of Health and UK Research and Innovation, underscoring their critical role in modern open science practices. Looking ahead, future sessions will cover digital preservation strategies to ensure data longevity, registration templates for structured project design, and advanced usage of the OSF API. Additionally, new self-paced training modules on topics like pre-registration and data management are available for researchers seeking to build practical skills throughout their research lifecycle. By adopting these identifier systems now, scholars can contribute to a larger global network that makes it easier to discover, cite, and connect valuable research contributions across disciplines and institutions.

Hello everyone, welcome to our webinar
today. Um, as folks are coming in, I
will just welcome you. Uh, this is the
latest in our 2026 series of OSF
Essentials webinars. Uh, these are focus
sessions on different topics each month
built around the questions, workflows,
and practical needs that users most
often want help with. Uh, so join us on
the last Thursday of every month. We
have three or four more of these
scheduled for this year. Um, this month
we're going to talk about persistent
identifiers, otherwise known as PIDs,
and how to use them on the OSF. Um, I'll
have some more information as well at
the end of our session about our future
series of webinars and other training
opportunities from Center for Open
Science.
So, just some reminders before we get
started. Um, please use the Q&A box for
questions. This should be towards the
bottom of your screen, probably in your
Zoom controls. Um, it says Q&A. Um, type
your questions in there. It will be much
easier for us to track them and make
sure that we get them answered. Um, you
can use this the chat, however, to
introduce yourself or or make comments.
Um, but we do end up missing questions
if they end up being in the chat rather
than the Q&A.
And just as a reminder, you will receive
an email with the recording of this
session and the slides um probably early
next week. So, um, don't worry if there
are URLs that show that you don't get to
copy down in time. You will receive the
slides with all those links.
So, let's get started. Today, we're
specifically going to talk about
persistent identifiers or PIDs and what
they are. Then, we'll talk about how
PIDs improve research. And finally,
we'll talk about using PIDs on the OSF.
Okay. So, what is a persistent
identifier? Uh, persistent identifiers,
PIDs, are globally unique, persistent,
interoperable, and machine readable
identifiers. So, essentially, they're
unique numbers assigned to people,
places, or things by an organization.
But it's not enough to just be unique.
That organ organization that creates the
number has to have a guarantee that they
will maintain it. those organizations
register or mint the identifiers and
then keep a consistent record for them
and if it's a web- based resource make
uh also the URL where they can be found
so that moving forward you can always
find that resource because the URL gets
updated by the organization
in repositories we're primarily talking
about people who create and contribute
to works the organizations that are
associated with them and the work
objects they produce the articles, the
papers, the data sets.
Okay, so PIDs are unique and persistent.
But what's the point? Well, sometimes
the identifiers are used primarily to
disambiguate or distinguish between
between things. So you can see here just
part of a list of people named William
Smith. The identifiers here work to
distinguish one William Smith from each
other.
When works that William Smith creates
use this identifier to refer to him, we
can easily create a list of all of the
works associated with one William Smith
over another.
Another way you're probably familiar
with PIDs is when they're used as links
to publications like these DOIs.
When PIDs are used as links, they're
sometimes known as uniform resource
identifiers or URIs.
That's very similar to universal
resource locator or URL which you may be
familiar with. The difference is that
the URI is a persistent link from an
organization committed to resolve the
link to a document in the future.
Digital object identifiers or DOIs are a
widely used PID for objects in the
research environment.
But there are also persistent
identifiers for objects uh from other
organizations with other names such as
arcs, handles and pearls.
We when we can link PIDs within a system
within a repository for example we can
create an infrastructure based on those
persistent links. So this means that in
OSF for example when we store data we
don't have to store data about the same
person or the same organization multiple
times in multiple records possibly
spelling it multiple ways or creating
other inconsistencies.
So let's say we have this object in OSF
and it's created by this user for a
project funded by this institution.
Each entity, the person, object or
organization in OSF has an ID, either an
OSF, what we call a GID, which is
unique, a unique identifier, but not a
PID. And then uh they may have another
persistent identifier like orchid for
this person and auror ID for this
institution. Talk a little bit more
about those in a second.
in the OSF object. Then we only have to
store the identifier and not all the
information. When we present this
record, when we present back to you
information about this object, we can
fill in the correct name or other info
from the source record. And then the
identifier can be used over and over
again in all records. So here is the
same identifier for this creator in
another work that they've created.
When PIDs are assigned relationships to
one another like this, it makes what's
called an information graph. So this
user has uh an orchid which is shown
here and they are uh they work for this
organization which has what's called a
roar ID for research organization
registry.
This user then creates this work which
has a DOI which is a digital object
identifier.
That DOI is in turn published in a
collection volume that has its own DOI,
a separate DOI. So the power of graphs
then is that they can be used to infer
and expand relationships. So if I know
the text was written by this user and
this user is affiliated with this
institution, I can by inference
associate the text with the institution.
Creating graphs of PIDs based on
relationships between identified items
instead of just flat individual records
allows you to answer more complex
questions.
So in the graph here which is the image
on the right going to annotate a little
bit. Um the question is I want to find
all digital objects that are connected
to a research object. In this case I'm
interested in this one right here.
So I can tell by looking at that object
that it has a relationship to this one
and it has a relationship
to this one. But in addition, these two
objects have other relationships to
these other objects.
So by
uh putting these all together, I now
know that there is an inferred
relationship between this object and
that and
the uh original text and this other
record.
So this allows us to visualize the real
impact of the relationship that this
work has had to all of these objects as
opposed to just the ones that are listed
in the bibliography. For example,
by aggregating records that use the same
identifier from more than one
repository, more information about those
items can be pieced together. So if OSF
shares our graph data, um that can be
used by other organizations, they can
combine it with their own to build a
bigger and better overall graph. And
since OSF is itself multiddisciplinary
and multi-institutional, we can reveal
relationships that might otherwise be
difficult to surface.
Hold on. There we go.
Pardon me. I'm having a little
There we go. So, the end goal is to
create an even larger network of graphs
that can connect more information and
help uncover more types of relationships
and connections that might have been
difficult to detect. This is a graph of
biblometric data about journals and it
shows connections between titles in
seemingly unrelated areas. Other graphs
could show networks of researchers and
their interests which could inform
decisions about research support or
potential collaborations.
Graphs with this level of breadth and
scale are possible through PIDs and
networks of shared information.
PIDs are so important and powerful in
fact that they're the number one item on
the National Institute of Health in the
United States list of desirable
characteristics for data repositories.
Um they're also highly ranked on the
National Science and Technology
Council's list of desirable
characteristics. PIDs also appear in the
UK research and in innovation UKRI open
access policy plan S requirements and
appears in the core trust seal
requirements. You may not know what
those organizations are, but they're
basically organizations that verify that
the work we do in repositories to make
sure that your research work is
disseminated and uh persists. Uh those
are organizations that ensure that that
happens. NIH specifically requires that
a repository assigns data sets a citable
unique persistent identifier such as a
digital object identifier to support
data discovery, reporting, and research
assessment. The identifier points to a
persistent landing page that remains
accessible even if the data set is de
accessioned or no longer available.
So in OSF we uh primarily use three
types of PIDs. PIDs for three different
things. We use what's called orchid for
users, roar for organizations and for
funding agencies
and DOIs coming from data site and
crossref for um OSF objects. Crossref is
an organization that registers DOIs for
preprints and other written works while
data set uh data site registers DOIs for
other types of content like data sets.
If you're comfortable with code, this
slide shows how these identifiers
actually get into the metadata that we
share in objects in OSF. If you aren't
though, don't worry. I'm going to talk
us through it. So, in this top example,
I've highlighted, you can see the
affiliation identifier, which is a URI
containing roar.org
right here. And we can see that it's
labeling the value University of Oxford.
So, now we have the PID and the name of
this organization.
Later in the record, we also see how
PIDs can help build relationships. In
these three fields, I'm referencing
three other related items to the work
that we're describing here. [snorts]
So, one is a version
and it resolves to a DOI. Um, this is
missing the prefix for the DOI, but
that's how DOIs are are format
formatted.
Next, we have a supplement that resolves
to another OSF object. And finally, this
object refers to a GitHub repository.
So, it's really simple, but this is how
the magic happens.
um we create this record, we pass it
along to say data site and then they can
sync up the document with the version
listed here, the other document that's a
version or other things from this
organization or uh other records by this
person. There's an orchid in this record
as well which you can find if you want
uh to have a little adventure. Um
so uh by using these identifiers in data
site they can aggregate together
information on all of these uh all of
the works by this person all of the
works from this organization etc.
So PIDs enable a graph of information in
OSF but because we share metadata in
other places we expand the graph into
other places. So I just showed you what
that looks like in term of the record
that we share but let's look at an
example. In this example, the user has
added their Orchid ID to their account.
They then uploaded a preprint to our
servers and it was assigned a DOI which
was registered with crossref.
So now that preprint shows up in crossre
and we were able to add the user's
orchid ID to that metadata. This means
the citation can also be scooped up into
the user's orchid profile. And all the
user had to do in this case was add
orchid to their account. Everything else
happened automatically because of the
way we register PIDs for preprints and
share metadata.
In another example, this user has also
added an orchid and they have also been
affiliated on the OSF with their
university through our institutional
membership program. So when we
registered a DOI uh for this person's
project with data site, we were able to
pass along the person's name but also
the organization that they're a part of.
So the resulting record and data site
has all of that information.
So these examples show how PIDs can
reduce administrative burden. In these
cases, one resource orchid for example
benefit benefited from the data in
another resource OSF.
In addition to PIDs always resolving to
something, if you use m machine readable
data standards and PIDs like this, we
can obtain the full metadata for the
resource at the PID location, which can
then be harvested and reused like I've
shown. In an ideal scenario, a
researcher administrator only needs to
populate metadata in one system one time
to then see it propagated down the line.
So, would you like to make some PIDs? I
hope so. Uh, I'm going to talk about
ways you can use PIDs in OSF. You can
add PIDs to your content in a couple of
ways. Um, this will help to build a
knowledge graph about yourself. The
first is to create an Orchid for
yourself if you haven't already. You can
do that at orchid.org/ org/register.
Once you have your Orchid, you can then
allow it to autoupdate. This will grab
references to things you publish that
get a DOI and publish them to your
Orchid record automatically.
Later on, when someone looks at your
Orchid record or another tool you use,
pulls in information about you from
Orchid, it will have all of that
information.
Finally, then you can associate your
Orchid with your OSF account. You just
choose to sign in with Orchid and use uh
your same username and password you
already have. You'll then go through a
verification pro process and the
profiles will be connected. This whole
process is described in the help guide
listed at the bottom of this slide and
again you will receive a copy of these
slides. So don't worry if this sounds
like a number of steps. We have it all
in a walkthrough in this guide.
So now every time you create a DOI for
something on OSF, if you've connected
your Orchid, it will get picked up into
your Orchid record.
Another way you can really leverage the
use of PIDs and OSF is to ensure that
you've created good metadata for any
object that you get a DOI for.
When you create a DOI in OSF, we send a
metadata record to data site or crossre
like I've shown, depending on what type
of material it is. They create a link
and then redirect to your OSF content.
They have committed to keeping those
links links persistent. One advantage of
having a DOI instead of just an OSF
record or OSF URL is that publishers,
repositories, aggregators and other
providers of research information use
DOIs to identify research work
precisely.
data site and crossref not only maintain
that PID, they also keep a catalog of
all of the material that has DOIs. So
all those publishers and repositories
can use um can get access to that
metadata and create more places your
work gets disseminated.
In addition to just creating DOIs for
your OSF content, you can link to DOIs
or other materials from your
registrations. These show up as badges
on the registrations. You can add DOIs
for data, materials, analytic code,
papers, and other supplements. Then when
someone comes to your registration and
learns about what you have planned for
your project, they can immediately find
out what your actual outputs and
outcomes are. Creating those links is
simple. From the registration overview
page, you select any resource icon and
those icons start out not colored in. Uh
once you select the icon you want to um
fill in, you see a window will open
where you can add the resource by adding
the DOI and and picking what type of
content this is. And then once the
resource is linked, it will show up with
a colored icon. And you can add as many
resources in these categories as you
want. Multiple data sets, multiple
papers, multiple uh types of code.
You can also enrich enrich your
preprints with PIDs for
pre-registrations, supplemental
materials, and published versions of
papers.
So remember this slide. Once you start
adding PIDs like orchids and DOIs to
your OSF content, you start to create
your own graph of information about your
research activities.
[snorts]
As an example, this is my orchid record
and I have publications showing here
that were added from the MLA
international bibliography and Scopus.
So, it's benefiting me to have used
those pits to have registered my orchid
um and set up that automatic uh update
in my orchid record.
So lastly, I've included this picture of
my cat in every other OSF Essentials
webinar I've done. So I felt like I had
to include it before I ended today. Her
name is Clementine, and she would like
to know if you have any questions. So at
this point, you can put questions, as I
said, in the Q&A. I will give you a
little bit of time to do that. And while
we wait, I'll tell you
about our upcoming OSF Essential
sessions. So next week uh next week next
month um we're going to talk about
digital preservation and research data.
Data is very easy to duplicate but it's
actually very hard to preserve. So um
we'll take a look at the basic needs of
digital preservation and give you tips
and strategies to ensure the longevity
of your work. Then we'll talk about
registration templates on the OSF in
September and we'll talk about how to
use the OSF API in October.
We've also launched a new series of
self-paced training opportunities that
help researchers build practical uh
skills across the research life cycle
using open scholarship practices. Um the
first three courses are available now.
Fundamentals of open scholarship,
pre-registration and registered reports
and data management and sharing. And
we'll have more courses coming
throughout 2026. You can also get badges
for the completion of this uh of these
modules. So, you can find out more at
cos.io/training/selfpaste.
All right. So, I'm going to go back to
our questions and if I can find it. Do
we have any?
[clears throat]
So, the question in the chat is if you
have an institutional membership with
OSF and then end it. If someone while
you had the membership had the roar
included with their OSF account, will it
remain there for metadata purposes? So
uh no it won't show in OSF but the data
site record won't be updated right away.
So it will remain in data site for a
while. Um but maintaining the the roar
is part of the in in the record as part
of the the membership
um service.
I see we have um we don't have any other
questions at this time. I'll give folks
another minute if they'd like to add
anything. Just check if there was
anything in the chat.
Doesn't look like it.
Okay. Well,
we can go ahead and wrap up for today.
This was a quick one, but um hopefully
it was enough to show you how PIDs can
help you um
make the most of your research. So, like
I said, you'll receive an email um
either in the in the next few days,
probably early next week, that will have
a link to this uh recording as well as
the slides and the links that were
shared. So, thank you everybody. Have a
great rest of your day. Bye.
