Cache attributes

DRAFT, WORK IN PROGRESS

A geocache may have attached a number of attributes, giving more information about the cache, the hiding, the recommendations, requirements, permissions, hazards, other helpful information related with the search.

This document describes the existing cache attributes across Opencaching sites.

IMPORTANT!!! As of 2019-06-01 the matrix below describes next generation attribute mappings, which is a work in progress implementation.

Attribute numbering rules

• all OC that have equivalent meaning to a GC attribute to use the same numeric ID; (while the meaning is equivalent, the exact wording of it's name need not be the same. examples are "bring your children / suitable for children / kids friendly / etc");
• all OC that have equivalent meaning to a negated GC attribute to use the same numeric ID added to 9000. (for example: "available 24/7" is ID 13. "NOT available 24/7" to be ID 9013.);
  • DE branch negated attributes use a separate flag and retain the ID without adding 9000.
• OC that have equivalent meaning on both PL and DE branches
• existing DE branch only attributes to retain their IDs in the range 100 - 199;
• all OC future and existing attributes that are PL branch specific to have numeric IDs in the range 200 - 299;
• all OC future attributes that are DE branch specific to have numeric IDs in the range 300 - 399;
• all OC special purpose attributes to have numeric IDs in the range 900 - 999;
• all OC that have the meaning of a negated OC attribute to use the same numeric ID on the least significant 3 digits, the fourth digit be the branch designator (according to applicability) and the fifth (most significant digit) be 9; (hypothetical generic example: "available during high tide" ID 241 - PL branch (UK), "NOT available during high tide" ID 9241 - PL branch)
• all attributes have assigned a unique ACODE (according to OKAPI).
• all "OC only" attributes have assigned a unique OCGS number, equal to their [public] ID. (for GPX export purposes).

Attributes matrix

OC attributes mapping

Every OC installation has its own set of internal attributes.

Some attributes are common between OC sites; some attributes are common with GC; some attributes are OC only; some attributes are specific to only some OC sites but not all.

OKAPI provides a unified interface for information exchange with third party apps (eg. c:geo) using GC compatibility and OC extensions (GPX export function).

Opencaching-PL implementation specific

All attributes are implemented as either ON or OFF; Inverse meaning is handled by a different attribute.

At this time attributes are defined in database (table cache_attrib). Each node has it's own attribute set, hence it's own contents for this table.

Each node must ensure the contents of this table follows the above numbering scheme.

Opencaching-DE implementation specific

Attributes are implemented with a unique internal ID, a separate public ID (same as GC ID where applicable; same as OCGS where applicable) and uses a flag to indicate normal (inc=1) / inverse (inc=0) meaning.

OKAPI implementation specific

OKAPI uses an internal mapping file attribute-definitions.xml.

OKAPI defines an internal ACODE to individually map attributes from each node and also to handle OC to GC equivalence.

OKAPI defines an additional pseudo-Groundspeak ID ("OCGS" IDs) for Opencaching attributes which have no Groundspeak equivalent, used to store such attributes in GPX <groundspeak:attribute> elements. "OCGS" IDs are unique and do not overlap with Groundspeak attribute IDs.

GC reference

Reference documented for establishing equivalences necessary for compatibility with third party apps using GPX file.

• Attribute has only YES = attribute that can be set or unset;
• Attribute has both YES and NO = attribute that can be set normally, set as it's inverse meaning or unset;

Developers and node operators

All changes to attributes must follow the rules stated on this page.

Any attribute change must be implemented with the following considerations in mind:

• documentation here;
• implementation in the respective Opencaching branch(es), including GPX export module;
• implementation in OKAPI;
• notifying third party app developers of the change.

Creating a new attribute

1. Creating a new attribute must start with submitting an issue on the development page of the respective Opencaching branch(es), as a request for a new attribute.
2. All new attributes must follow the Attribute numbering rules above.
3. All new attributes must be properly documented here before implementation. That means inclusion in the Attributes matrix as well as their own descriptive page that will include a deplopyment date.
4. Developers will then implement the new attribute according to the Opencaching branch(es) involved and OKAPI attribute-definitions.xml.
5. Third party app developers to be informed of the change.

Adding an existing attribute

A certain Opencaching node may not have an existing attribute from the Attributes matrix.

1. Document the addition on the attribute's page.
2. Update OKAPI attribute-definitions.xml.
3. Deploy the attribute on the node in question according to the procedures for the Opencaching branch software used.
4. Third party app developers to be informed of the change.

Changing an attribute

Changing an existing attribute's meaning or purpose is not permitted.

The only change allowed is updating the attribute's descriptive text (including translations) to better convey it's meaning/purpose for reasons such as bad translation or poor word choice.

Removing an attribute

An attribute may be removed, but not completely deleted.

A removed attribute will be documented as strike-through text in the Attributes matrix and it's own page.

An attribute may be removed from one node, all nodes of a branch or all branches.

1. Document the removal of the attribute in the Attributes matrix and attribute page including planned removal date.
2. Update OKAPI attribute-definitions.xml. by removing the relevant node(s). Note: OKAPI forbids the deletion of ACODES even if not mapped to any node, for backwards compatibility reasons.
3. Remove the attribute usage from the node(s) database according to the procedures for the Opencaching branch software used.
4. Create an issue on the development page of the respective Opencaching branch(es) to remove the attribute if applicable.
5. Developers will then implement the change.
