SE-05 : Cultural Heritage

ICO Std 2002 — Extension SE-05

This extension module specifies the requirements and methodologies for ranking and evaluating cultural heritage, including tangible heritage, intangible cultural heritage (ICH), and heritage practices. It addresses the unique challenges of heritage assessment — including the valuation of attributes that resist quantification, the imperative of community participation, and the alignment with internationally recognised conservation frameworks. This module extends the core-layer methodology (Chapters 4 through 10) by defining domain-specific indicators, data collection protocols, and scoring procedures that reflect the particularities of cultural heritage evaluation. It is directly applicable to the Tianji Ranking intangible cultural heritage track and other heritage-oriented ranking initiatives.

SE-05.3 Indicator System

SE-05.3.1 Indicator Hierarchy

The cultural heritage indicator system shall be organised into the following three-level hierarchy:

a) Level 1 — Dimensions: Historical Value, Artistic Value, Scientific Value, Social Value, Endangerment Level, Authenticity, Integrity, Community Engagement, State of Conservation;

b) Level 2 — Sub-dimensions: Decompositions of each dimension as specified in SE-05.3.2 through SE-05.3.10;

c) Level 3 — Specific measures: Operationalised variables for which data is collected, as specified in each sub-dimension.

SE-05.3.2 Historical Value

Historical value assesses the significance of a heritage item in representing, documenting, or bearing witness to historical processes, events, or periods.

a) Antiquity: The temporal depth of the heritage item. The ranking entity shall define period classifications relevant to the cultural context (e.g., pre-modern, early modern, modern, contemporary).

b) Historical Representativeness: The degree to which the heritage item exemplifies a particular historical period, movement, or cultural development. Assessment shall reference established historiographical frameworks.

c) Documentary Evidence: The extent to which the heritage item is supported by archival, archaeological, or other documentary evidence. Items with rich documentary corroboration shall score higher than those relying solely on oral tradition, unless the oral tradition itself constitutes the heritage value.

SE-05.3.3 Artistic Value

Artistic value assesses the aesthetic achievement and creative significance of a heritage item.

a) Aesthetic Excellence: The degree to which the heritage item demonstrates recognised standards of aesthetic achievement within its cultural tradition. The ranking entity shall employ culture-specific aesthetic criteria and shall not impose external aesthetic standards.

b) Creative Innovation: The degree to which the heritage item represents innovation or creative achievement within its artistic tradition, including the adaptation of traditional forms to new contexts.

c) Influence on Subsequent Traditions: The documented or verifiable influence of the heritage item on subsequent artistic or cultural developments.

SE-05.3.4 Scientific Value

Scientific value assesses the contribution of a heritage item to knowledge generation, research, and understanding of natural or cultural phenomena.

a) Research Potential: The extent to which the heritage item offers opportunities for new research findings, including archaeological, anthropological, or scientific insights.

b) Information Content: The volume and quality of information that the heritage item preserves or encodes about past technologies, environments, social structures, or knowledge systems.

c) Methodological Significance: The degree to which the study of the heritage item has contributed to or may contribute to the development of research methodologies.

Social value assesses the contemporary relevance and societal significance of a heritage item, including its role in identity formation, social cohesion, and cultural continuity.

a) Identity Significance: The degree to which the heritage item serves as a marker of collective identity for a community or group. Assessment shall include the perspectives of the associated community.

b) Social Cohesion Function: The extent to which the heritage item contributes to social bonding, intergenerational connection, or community solidarity.

c) Contemporary Relevance: The degree to which the heritage item remains meaningful and functional in contemporary society, including its adaptation to present-day needs and contexts.

SE-05.3.6 Endangerment Level

Endangerment level assesses the degree of threat to the continued existence or viability of a heritage item. This dimension shall be assessed with urgency, as it directly informs safeguarding priorities.

a) Threat Assessment: The ranking entity shall identify and categorise threats using a standardised taxonomy that includes:

1) environmental threats (climate change, natural disasters, environmental degradation);

2) socio-economic threats (urbanisation, economic displacement, labour migration);

3) cultural threats (globalisation, cultural homogenisation, loss of transmission);

4) political and legal threats (armed conflict, inadequate legal protection, policy changes).

b) Transmission Continuity: For intangible cultural heritage, the ranking entity shall assess:

1) the number of active transmitters (practitioners, masters, apprentices);

2) the age distribution of practitioners, with particular attention to the absence of younger generations;

3) the existence and viability of formal or informal transmission mechanisms.

c) Viability Index: A composite measure combining threat level and transmission continuity. The ranking entity shall calculate the viability index using the following formula:

\[V = 1 - \frac{T_{\text{norm}} + (1 - C_{\text{norm}})}{2}\]

where $T_{\text{norm}}$ is the normalised threat score (0 = no threat, 1 = extreme threat) and $C_{\text{norm}}$ is the normalised transmission continuity score (0 = no transmission, 1 = robust transmission). Higher $V$ values indicate greater viability.

SE-05.3.7 Authenticity

Authenticity assesses the degree to which a heritage item’s cultural values are truthfully and credibly expressed through its attributes. This dimension follows the Nara Document on Authenticity (1994) principle that authenticity judgements shall be made within the cultural context to which the heritage item belongs.

a) Material Authenticity: For tangible heritage, the degree to which original materials, construction techniques, and physical fabric are preserved. The ranking entity shall assess the proportion of original fabric retained and the quality of past interventions.

b) Functional Authenticity: The degree to which the heritage item continues to serve its original or traditionally associated function.

c) Expressive Authenticity: For intangible cultural heritage, the degree to which the practice retains its essential character, meaning, and mode of expression as recognised by the associated community. Adaptations and evolutions that are community-driven and internally motivated shall not be considered losses of authenticity.

d) Contextual Authenticity: The degree to which the heritage item remains in its original cultural, spatial, or social context. Relocated or decontextualised heritage items shall have reduced authenticity scores unless the relocation itself holds heritage significance.

Note: Authenticity is not a binary quality. The ranking entity shall assess authenticity as a matter of degree along each sub-dimension, and shall document the cultural framework within which the assessment is made.

SE-05.3.8 Integrity

Integrity assesses the wholeness and intactness of a heritage item and the extent to which it contains all the elements necessary to express its outstanding universal value or cultural significance.

a) Structural Integrity: For tangible heritage, the physical completeness of the heritage item, including all constituent parts, spatial relationships, and visual relationships.

b) Systemic Integrity: The completeness of the cultural system or practice that the heritage item represents, including its associated knowledge, skills, rituals, and social structures.

c) Ecological Integrity: For cultural landscapes and nature-culture interlinked heritage, the degree to which the ecological processes and interactions that sustain the heritage values remain intact.

SE-05.3.9 Community Engagement

Community engagement assesses the degree and quality of involvement of the associated community in the identification, safeguarding, transmission, and management of the heritage item. This dimension recognises the principle established in the UNESCO 2003 Convention that communities, groups, and practitioners should play a central role in safeguarding intangible cultural heritage.

a) Participation in Identification: The degree to which the associated community was involved in identifying and defining the heritage item and its cultural values. Rankings shall not evaluate heritage items without evidence of community consultation.

b) Participation in Safeguarding: The extent and quality of community involvement in safeguarding measures, including:

1) the existence of community-initiated safeguarding programmes;

2) the allocation of community resources (time, labour, financial) to safeguarding;

3) the effectiveness of community governance structures for heritage management.

c) Inclusive Representation: The ranking entity shall assess whether the participation process includes diverse segments of the associated community, including:

1) gender representation among practitioners and decision-makers;

2) intergenerational participation;

3) representation of minority or marginalised sub-groups within the community.

d) Free, Prior and Informed Consent: Where data collection for ranking purposes involves access to community knowledge, the ranking entity shall obtain free, prior and informed consent (FPIC) in accordance with the principles set out in the UN Declaration on the Rights of Indigenous Peoples (2007).

SE-05.3.10 State of Conservation

State of conservation assesses the current condition of a heritage item and the effectiveness of measures taken to preserve it.

a) Physical Condition: For tangible heritage, a standardised assessment of the physical state using condition rating scales (e.g., excellent, good, fair, poor, critical) with defined criteria for each level.

b) Practice Vitality: For intangible cultural heritage, an assessment of the frequency, scale, and quality of ongoing practice, including:

1) frequency of regular practice (daily, weekly, seasonal, annual, irregular);

2) number of active practitioners relative to the total associated population;

3) quality of practice as assessed by community-recognised standards.

c) Safeguarding Effectiveness: An assessment of whether existing safeguarding measures have achieved their stated objectives. The ranking entity shall use before-and-after comparisons where baseline data is available.

d) Risk Monitoring: The existence and quality of ongoing monitoring systems for threats and conservation status. The ranking entity shall assess:

1) whether a monitoring system exists;

2) the frequency and regularity of monitoring;

3) whether monitoring data is publicly accessible or available for audit.

SE-05.4 Data Collection

SE-05.4.1 Data Source Categories

The ranking entity shall collect data from the following categories of sources:

a) Official Heritage Records: National and international heritage registries, tentative lists, and inscription dossiers (e.g., UNESCO World Heritage List, national ICH inventories).

b) Conservation Reports: State of conservation reports, periodic reporting documents, and reactive monitoring reports prepared by or submitted to heritage authorities.

c) Community-Based Documentation: Oral histories, community archives, ethnographic records, and participatory documentation produced by or with the associated community.

d) Academic Literature: Peer-reviewed research publications, dissertations, and field reports relevant to the heritage items under evaluation.

e) Expert Assessment: Structured assessments by qualified experts in relevant heritage domains (archaeology, anthropology, conservation science, traditional arts).

SE-05.4.2 Data Collection Protocols

a) The ranking entity shall develop a data collection protocol specific to each heritage ranking project. The protocol shall specify:

1) the list of indicators from Section SE-05.3 to be measured;

2) the data source(s) for each indicator;

3) the data collection method (document review, field survey, expert elicitation, community consultation, or combination);

4) the timeframe for data collection;

5) quality assurance procedures.

b) For intangible cultural heritage, the data collection protocol shall include provisions for:

1) the use of culturally appropriate communication methods;

2) the involvement of community members as co-investigators or cultural mediators;

3) the documentation of the consent process and any conditions imposed by the community.

SE-05.4.3 Handling of Intangible Knowledge

a) The ranking entity shall recognise that intangible cultural heritage knowledge may be sacred, secret, or subject to customary access restrictions. The ranking entity shall:

1) respect community decisions regarding the confidentiality of cultural knowledge;

2) not require the disclosure of restricted knowledge as a condition for ranking inclusion;

3) provide alternative assessment pathways where full data access is not possible.

b) Where community knowledge is used in ranking assessment, the ranking entity shall document:

1) the source and nature of the knowledge;

2) the consent obtained for its use;

3) any restrictions on further dissemination.

SE-05.4.4 Temporal Considerations

a) Heritage ranking data shall reflect the current state of the heritage item at the time of data collection. Historical data may be used for trend analysis but shall not substitute for current-condition data.

b) For intangible cultural heritage, the ranking entity shall account for the cyclical or seasonal nature of many heritage practices. Data collection shall be timed to capture practice at its most representative period.

c) The ranking entity shall document the date of each data point and the time elapsed between data collection and ranking publication.

SE-05.5 Scoring Methodology

SE-05.5.1 Scoring Scale

a) Each Level 3 indicator shall be scored on a scale appropriate to its measurement type:

1) Quantitative indicators shall use normalised scales (0 to 1 or 0 to 100);

2) Qualitative indicators shall use defined ordinal scales with at least five levels, each with explicit criteria and anchor descriptions.

b) Where expert judgement is required, the ranking entity shall use structured elicitation protocols (e.g., Delphi method as specified in Chapter 5 of the core layer) and shall report inter-rater reliability statistics.

SE-05.5.2 Weighting

a) The default weight scheme for the nine Level 1 dimensions shall be as follows, unless the ranking entity provides documented justification for alternative weights:

Dimension	Default Weight
Historical Value	0.15
Artistic Value	0.12
Scientific Value	0.10
Social Value	0.12
Endangerment Level	0.15
Authenticity	0.12
Integrity	0.08
Community Engagement	0.10
State of Conservation	0.06

b) The default weights reflect the principle that cultural heritage rankings shall prioritise historical significance, endangerment, and authenticity, while also recognising the importance of community agency and social relevance.

c) For rankings focused specifically on intangible cultural heritage, the ranking entity should increase the weight of Community Engagement and Transmission Vitality indicators to reflect the living nature of ICH.

d) Weight modifications shall be subject to the procedures specified in Chapter 6 of the core layer, including stakeholder consultation and sensitivity analysis.

SE-05.5.3 Aggregation

a) Scores at Level 3 shall be aggregated to Level 2 using the weighted sum method specified in Chapter 8 of the core layer.

b) Scores at Level 2 shall be aggregated to Level 1 using the same method.

c) The overall heritage score shall be calculated as the weighted sum of Level 1 dimension scores using the weights defined in SE-05.5.2.

d) The ranking entity shall report dimension-level scores alongside the overall score to enable users to understand the profile of each ranked heritage item.

SE-05.5.4 Special Provisions for ICH Rankings

a) For rankings of intangible cultural heritage, the ranking entity shall include a Transmission Vitality Index as a supplementary measure. The Transmission Vitality Index shall be calculated as:

\[TVI = \frac{P_{\text{active}}}{P_{\text{total}}} \times \frac{A_{\text{young}}}{A_{\text{total}}} \times F_{\text{practice}}\]

where $P_{\text{active}}$ is the number of active practitioners, $P_{\text{total}}$ is the total estimated practitioner population at peak, $A_{\text{young}}$ is the number of practitioners under 40, $A_{\text{total}}$ is the total active practitioners, and $F_{\text{practice}}$ is the practice frequency factor (1.0 = daily, 0.8 = weekly, 0.5 = seasonal, 0.3 = annual, 0.1 = irregular).

b) The Transmission Vitality Index shall be reported alongside the overall score for all ICH rankings and shall be used as a tiebreaker when overall scores are equal.

SE-05.6 Cultural Sensitivity and Ethical Requirements

SE-05.6.1 Cultural Sensitivity

a) The ranking entity shall ensure that the evaluation framework does not impose external cultural values or aesthetic standards on heritage items from different cultural traditions.

b) Where assessment criteria require culture-specific interpretation (e.g., artistic value, authenticity), the ranking entity shall include qualified cultural insiders in the assessment process.

c) The ranking entity shall not rank heritage items from incommensurable cultural traditions against each other without explicit contextualisation. Cross-cultural comparisons shall be accompanied by a methodological note explaining the limitations of such comparisons.

SE-05.6.2 Ethical Obligations

a) The ranking entity shall not publish rankings that may contribute to the commercialisation, exploitation, or misappropriation of cultural heritage.

b) Where ranking publication may increase visitor pressure or tourism development around a heritage site, the ranking entity shall include a conservation advisory note in the publication.

c) The ranking entity shall respect the right of communities to withdraw their heritage from ranking consideration. If a community requests removal, the ranking entity shall comply within one ranking cycle.

a) Where the ranking entity derives commercial benefit from heritage rankings, the ranking entity should establish mechanisms for benefit sharing with the associated communities.

b) Benefit sharing may include financial contributions to safeguarding programmes, capacity building, community development projects, or other forms as agreed with the community.

SE-05.7 Alignment with International Frameworks

SE-05.7.1 UNESCO World Heritage Convention Alignment

a) For rankings of tangible cultural heritage, the indicator system shall be consistent with the criteria for Outstanding Universal Value (OUV) as defined in the Operational Guidelines for the Implementation of the World Heritage Convention.

b) The assessment of authenticity and integrity shall follow the principles established in the Operational Guidelines, paragraphs 79-86 (authenticity) and paragraphs 87-95 (integrity), adapted as necessary for ranking purposes.

SE-05.7.2 UNESCO ICH Convention Alignment

a) For rankings of intangible cultural heritage, the indicator system shall be consistent with the definition and principles of the Convention for the Safeguarding of the Intangible Cultural Heritage (2003).

b) The ranking entity shall respect the Convention’s emphasis on the central role of communities, groups, and individuals in safeguarding ICH, as articulated in Article 15.

c) The assessment of safeguarding measures shall reference the definitions and categories established in the Convention and its Operational Directives.

SE-05.7.3 Nara Document Alignment

a) The assessment of authenticity shall follow the principles of the Nara Document on Authenticity (1994), particularly:

1) that authenticity judgements must be linked to the cultural context within which the heritage item exists;

2) that the attributes against which authenticity is assessed may include form and design, materials and substance, use and function, traditions and techniques, location and setting, language and other forms of intangible heritage, spirit and feeling, and other internal and external factors.

SE-05.8 Publication and Transparency

SE-05.8.1 Publication Requirements

In addition to the requirements specified in Chapter 9 of the core layer, heritage ranking publications shall include:

a) a statement of alignment with the international frameworks referenced in SE-05.7;

b) the cultural sensitivity assessment conducted under SE-05.6.1;

c) for ICH rankings, the Transmission Vitality Index for each ranked item;

d) a conservation advisory note, where applicable.

SE-05.8.2 Community Notification

a) Before publishing a heritage ranking, the ranking entity shall notify the associated communities of the intended publication and provide a reasonable period (not less than 30 calendar days) for community review and feedback.

b) Community feedback shall be documented. Where communities raise substantive concerns about cultural sensitivity or potential harm, the ranking entity shall address these concerns before publication.

Note: This extension module is part of ICO Std 2002 (Tianji Ranking Methodology Standard). Cultural heritage evaluation presents unique methodological challenges arising from the diversity of cultural traditions, the intangible nature of much heritage value, and the ethical imperative of community participation. Ranking entities should approach heritage evaluation with humility and cultural awareness, recognising that quantification can never fully capture the meaning and significance of cultural heritage to its associated communities. The indicators and methods specified in this module are intended to provide a structured and transparent framework for heritage assessment, not to reduce cultural heritage to numerical scores alone.
