## Instance
An instance is one specific materialization or version of the result. For example, you can have one result with three instances as result of deduplication:
* one is the pre-print
* one is the post-print
* one is the published version
Each instance is characterized by the properties that follow.
Maps [dc:rights](https://www.dublincore.org/specifications/dublin-core/dcmi-terms/elements11/rights/), describes the access rights of the web resources relative to this instance.
The set of persistent identifiers associated to this instance that have been collected from an authority for the pid type (i.e. Crossref/Datacite for doi). See the [OpenAIRE entity identifier and PID mapping policy](../pids-and-identifiers) for more information.

This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.
This is an alternative to the "Popularity" indicator, which also reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.
Indicates the reason why this country is associated to this result.

<!-- <span className="todo">Seems to be similar to the AlternateIdentifier. What is the difference?</span> -->
### scheme
_Type: String • Cardinality: ONE_
The scheme of the persistent identifier for the result (i.e. doi). If the pid is here it means the information for the pid has been collected from an authority for that pid type (i.e. Crossref/Datacite for doi). The set of authoritative pid is: `doi` when collected from Crossref or Datacite, `pmid` when collected from EuroPubmed, `arxiv` when collected from arXiv, `handle` from the repositories.
```json
"scheme": "doi"
```
### value
_Type: String • Cardinality: ONE_

```json
"value": "10.21511/bbs.13(3).2018.13"
```
## Score
The specific score object for each calculated impact measure calculated by [BIP!](https://bip.imsi.athenarc.gr/).
### score
_Type: String • Cardinality: ONE_
The actual indicator score.
```json
"score": "1234"
```
### class
_Type: String • Cardinality: ONE_
The impact class assigned based on the indicator score.
To facilitate comprehension, BIP! also offers impact classes for articles, to group together those that have similar impact. The following 5 classes are provided:
The value for the subject in the selected scheme. When the scheme is 'keyword', it means that the subject is free-text (i.e. not a term from a controlled vocabulary).
```json
"value" : "pyrolysis-oil"
```
## UsageCounts
The usage counts indicator computed for this result.
