1. What is a persistent identifier?

A PID is a unique string of alphanumeric symbols characterizing a digital resource. It is meant to be processed by a resolver to produce a Universal Resource Locator (URL) pointing at the resource or launching a process for the display or downloading of document(s). The latter is applicable to documents subject to authentication and assessment of access rights.

For instance, PID “hdl:11041/swedia-000788” points at a speech corpus named “Swedia 2000” available from SLDR. Expression 'hdl:' indicates that the PID makes use of the Handle system. Therefore, to reach this resource the PID should be 'resolved' by a Handle server. This is achieved by appending its value after the resolver’s URL: http://hdl.handle.net/11041/swedia-000788 (or installing a plug-in for resolving Handles in Firefox). This handle points at the item whose canonic URL within SLDR is www.sldr.org/swedia-000788. Its is persistent because it does not mention “sldr.org”. Instead, it makes use of “11041”, a prefix assigned to the SLDR/ORTOLANG repository in the Handle domain.

A PID may also be assigned to a particular file. By default, all files contained in an item are assigned PIDs. Exceptions may occur for secret files (never shared) or files wrapped in an archive (e.g. zip or tar) that will never be downloaded separately.

2. Some practice / Un poco de práctica

3. What is in a PID?

PIDs on SLDR contain no string of random characters. Therefore it is possible for an experienced user to guess what will be the PID of a single file in an item. For instance, hdl:11041/prax000824/DISPOSITIF.zip is the concatenation of four identifiers:

4. Downloading or browsing?

5. Item versioning

Each version of an item requires a different PID. For instance, item “sldr000018” is available in 2 versions whose PIDs are respectively:

Rule 1: A PID that does not contain a version number shall point at the latest version of its target resource.
Thus, currently hdl:11041/sldr000018 points at the same information package as hdl:11041/sldr000018_v2. This rule is convenient for users eager to fetch the latest version of an item or document regardless of its modifications.

6. Using canonic PIDs

PID hdl:11041/sldr000720/CID-publications-Bilan2010.txt points to document "CID-publications-Bilan2010.txt" in the current version of item sldr000720. This raises two questions:

  1. What will happen if the producer uploads a new version containing a file named "CID-publications-Bilan2010.txt"?
  2. What will happen if this version of the item contains more than one file named "CID-publications-Bilan2010.txt"?

In response to question (1) SLDR applies the following rule:
Rule 2: A document that is not modified across successive versions of an item should be accessible via the same canonic PID.

Consequently, canonic PIDs do not contain the version number of the item in which the document will be fetched.

In response to question (2) SLDR applies the following rule:
Rule 3: Identical documents in an item share the same canonic PID, regardless of item version.

Documents are considered identical if:

  1. Their content is identical. This is checked by a cryptographic hash function assessing data integrity (MD5);
  2. (Short canonic PIDs): their filenames are identical;
  3. (Long canonic PIDs): the tails of their paths and their filenames are identical.

6.1 Indexed filenames

Short canonic PIDs only refer to the item and the file name of a document in that item. If the item contains several documents with identical file names, two situations may occur:

  1. For documents with identical content (same MD5) the same PID will be used;
  2. For documents with different content the system will automatically append an index to the file name in the PID.

For instance:

Option 1: indexing is displayed starting with 2 instead of 1.
This option is set by default and forced in directories §autorisations and §licence. It may be unchecked when repetitions are significative, e.g. http://hdl.handle.net/11041/ortolang-000900?urlappend=/toc.

6.2 File extensions

Option 2: PID and file extensions
In the default option, a PIDs terminates with the file extension, e.g. hdl:11041/sldr000018/catalogue.pdf
If the althernative option, the PID would be 'hdl:11041/sldr000018/catalogue'.

Technical note: SLDR provides MIME types in the headers of downloaded files. For this reason a browser would guess the type and suggest appropriate action even if the extension is not displayed.

Implementation in SLDR:

Suggestions:

An example of removing extension 'csv' is displayed on http://sldr.org/BeQuali-000532/toc. Thus, for instance, the canonic PID of file 'meta_documents.csv' is hdl:11041/BeQuali-000532/meta_documents.

6.3 Options for short canonic PIDs

When PID is short, it is possible to append before the file name all or part of the path that locates it. The rewritten name will then be the new PID.

Canonic PIDs are set to 'short' by default (no path information). This covers the case when each file name is a unique identifier of the file within an item, or we allow the PID creation algorithm to append an index after identical file names when these designate different documents.

A 'long' canonic PID is one that would contain the path to the document. This option should be avoided because it forces the system to create a new PID each time the file is moved to another part in the hierarchy.

Specifications for path inclusion:

The following options (3 and 4) may be applied to short canonic PIDS.

Option 3: Include tail of file path in PID

Suggestions:

An example is displayed on http://sldr.org/sldr000002/toc. Files named '10681131.wav' are not identical because they contain a distinct track of the same recording. Therefore a consistent identification should contain the channel number. This is achieved by setting 'tail depth' to 1, e.g.:

Option 4: Include head of file path in PID

An example is found in http://sldr.org/alipe-000853/toc with head depth = 1, tail depth = 0 and discarding 'html' extension:
