FRIDA KAHLO

About FRIDA

Study of the domain

Frida Kahlo was a revolutionary individual. She reacted against the pain she faced throughout her life.

Born on 6th July 1907 in Coyocoan, Mexico City. Even though she declared to be born in 1910 to be a symbol of the Mexican Revolution

Frida, as many Mexican artists working after the Revolutionary decade that began in 1910, was influenced by the nationalistic fervor of the Mexicanidad. These artists rejected European influences and found expressivity in folk tradition, as well as, in their country’s native roots.

She grew up at the Blue House: now a museum dedicated to her life and to Mexican art. The house is blue, like the open sky.

Frida suffered from poor health since she was a child: she caught poliomyelitis when she was six, causing a foot deviation. This is the reason why she wore long skirts. She used to paint self-portraits to depict the subject she knew the most: herself. The portraits often captured her strong brows and deep stare.

As for education, she attended the National Preparatory School of Mexico City in 1922 where she distinguished herself for her bravery, this is where she met Diego Rivera for the first time.

Kahlo joined Los Cachuchas when she was 14, it was a political group named after the peaked cloth caps they wore, as a sign of subversion against the rigid dress code of the period. One of the most influential participants at this party was Gómez Arias, with whom she had a relationship.

In 1925 she was injured badly at a tram crash: her spine, pelvis, and hips were permanently harmed. She had to stay in hospital for a long time, so she started painting in bed, not to think about the pain she was going through.

She reconnected with Diego Rivera in 1928, they were free together traveling the world, fighting for the Mexican Revolution. Although their relationship was conflictual: they both had affairs with other people and were separated a lot of times, but they still always went back together.

It is possible to see Frida’s influences and her artistic process in her personal diary. Frida never stopped expressing herself in the truest way possible, influenced by Surrealism, her mind was an open pond.

Her art was displayed for the first time in 1931 at the yearly meeting of the Women Artist Society, today. Between our items we considered also the photographs displaying Frieda with the exiled Russian revolutionary leader Leon Trotsky. She wanted peace, that’s why she changed her name to Fried(a), to protest against German Nazis. When Frida had a miscarriage, she painted the Henry Ford Hospital (1932) in which the main subjects are her blood and interrupted pregnancies, in this desolate environment, she finds the courage to use blood to nourish plants.

Nickolas Murray was a lover and a good friend for Frida, they had epistolary exchanges since 1937. Murray was a photographer and took more than 60 pictures of Frieda during their 10 years of relationship.

Her portraits became more symbolic when she painted the Broken Column in 1944: the religious imagery and desolate landscape are a mirror of her mental state. She started wearing corsets to protest and offer her truest emotions. Her pain is a constant in all her works.

"I'm not sick. I'm broken. But I'm happy to be alive, as long as I can paint." | 27 April 1953.

Although her relationship with the Communist Revolutionary, Leon Trotsky, only lasted a few months, the artist was deeply influenced by the Mexicanidad movement. Frida and her husband Diego, hosted Trotsky and his wife. Frida and Trotsky had an affair, but after some time they remained friends. As Stalin’s power grew, Trotsky’s supportered diminuished: he eventually got killed. Frida was questioned about his death but it was stalinist supporter who accomplished the murder.

She thanked Nickolas for sending her money with a pseudonym, but she also tells him that she has finances and doesn't need help.

La casa Azul

Frida Kahlo Museum

Learn more

La Casa Azul is the ultimate universe of Frida Kahlo. It is the place where she was born and where she spent the majority of her life. It was her intention to leave it as a memorial to herself, that’s why Rivera turned it into a museum after her death. This house contains both artists’ paintings, pre-Columbian sculptures, photographs, books, and clothes (corsets and Tehuana dresses).

1933 Article by Diego Rivera, the first art critic on Frida

Diego Rivera's Article

Learn more

In this article, Diego firstly displays the history of the founding cultures of the Pre-hispanic and Spanish periods and the 19th century. Mexican artists reclaimed their independence after colonialism. There were 2 main art streams: those who copied Picasso and Dalì, and those who expressed their personality and mind through art, like Frida did. This article represents one of the first art critics on Kahlo's Art.

The Broken Column: Painting

The Broken Column

Learn more

In 1925 Frida was injured on a tram accident which crashed on a car at 18 years old. Pain and suffering are a constant topic in Frida’s painting. In this symbolic painting the split in her torso looks like an earthquake fissure. Dressed with a hospital sheet, a broken column is put in place of her spine, looking like she is breaking into pieces. She has tears on her face, but she sends a message of moral triumph.

Photo of Kahlo by Muray

Portrait by Nickolas Muray

Learn more

Nickolas Muray was Kahlo’s friend and longtime lover. He took photos of the mexican artist between 1937 (after 6 years into the relationship) and 1948, they worked together in order to frame and compose the pictures. These 90+ scenes show Kahlo's resilience and individuality, as well as the most vulnerable moments of her life. Her Tehuana dresses are shown often.

Frida’s diary is a collection of notes and drawnings. It was a way of connecting with her own feelings, and conveying her ideas in her artistic practice. Symbolism is present throughout her diary. Blue is the color of electricity and purity, while yellow represented madness, illness, fear, sometimes the sun, and happiness. This online exhibition hosted by Google Arts and Culture keeps Kahlo's memory alive.

   

Knowledge Organization

   

Conceptual Map

The main topic of our project is Frida Kahlo: a Mexican revolutionary painter. The items we have chosen are all relevant in order to tell the truth about her story. The purpose of our conceptual map is to represent the extracted data, all in natural language. This step represents data as extracted from the items and also the relationips between them. All purple nodes in the graph represent the items, while orange nodes represent important events and people related to the main subject.

E/R Model

This second model displays data and relationships from the conceptual map in a more abstracted layer. Here we represent people, dates, subjects, places etc. as entities and the connections between them as relationships.

Metadata Analysis

All standards allow computational modeling, helping mediate through different cultural heritage sources. All standards refer to cultural works.

The documentary hosted by Imdb-online informative database links television series, home video and television content online- we chose to use Schema.org because it is an appropriate schemas to deal with cinematographic items. Regarding the bibliography, it was under the Internet archive institution, it followed MARC standard.

As for Trotsky and Kahlo photography, the representation of Wikimedia Commons doesn’t follow any specific standard, hence we chose CIDOC-CRM suited for archival data. The portrait of Frida Kahlo is held by the MET Museum: an institution that adopts the CCRel license properties, but enhanced through Getty vocabularies; for this reason we selected CDWA to be the fittest standard. The Ted Educational Video is present both on Youtube and Ted-Talk: these institutions don’t follow any specific standard, but we decided to opt for the highly general Dublin Core standard.

The Diary is both an exhibition and an object itself, we chose the exhibition as an item event, being hosted on Google Arts and Culture, the museum "La casa Azul" did not have a standard, so we chose to adopt CCO- Catalogue for Cultural Objects: content standard for the descriptionof works of art, architecture and material culture. Its attempt is that of meeting the needs of both usual resources and museum communities.

The letter held by the American Archive of Arts, but we could not find their used metadata standard, so we decided to use the MARC standard to represent it; while the museum represented by ISNII follows Marc21.

As for the Article we e-mailed ICAA to know their adopted standard, they were under the supervision of Getty vocabularies for property choices, so we decided to adopt CDWA.

The order of metadata standards is equal to their relevancy to the project. In order to display the standards we retrieved ourselves we have displayed them with a (*).

  • 1. SCHEMA.ORG: a collaborative activity that creates and maintains schema for structured data for the Web. Founded by Google and Microsoft, it constitutes a shared vocabulary for extensible experiences.
  • 2. Dublin Core: allows the bridging of established metadata and graph-based solutions for integration across data within a Linked Data ecosystem. Made up of 15 metadata elements, it offers expanded cataloging information and improved indexing for search engine programs.
  • 3. CIDOC-CRM CIDOC-CRM - Conceptual Reference Model, it is a theoretical as well as a practical tool to extend and integrate cultural heritage information. Allows the retrieval of specific data points. It defines concepts and relationships essential for the analysis of Cultural Heritage materials.
  • 4. CDWA/CCO Categories for the Description of Works of Art. It is a data standard of art and its disciplines. This core offers a conceptual framework for retrieving information. It can be used to map data, identify issues, and openly link data.
  • 5. MARC/MARC21. A MARCXML standard, offering detailed descriptions of data elements, enriched with historic sections.
  • 6. CCO: Cataloguing Cultural Objects. This guide is the first data content standard specifically intended for cataloging cultural heritage material. Following the development of metadata sets such as CDWA and Dublin Core, CCO syntax guides the choice of terms for ordering data. Cataloging of all cultural works: paintings, sculptures, objects of material culture, architecture/built works, installation art, performance art, manuscripts, photographs, and prints.

Metadata Alignment

After having found the linked institutions and corresponding standard, this last fundamental step allows the final description and interconnection between items. The whole purpose of this project was to adopt shared semantic ontologies in order to deliver coherent data.

    The final adopted standards:
  • 1. Dublin Core : dcterms. Applied over most standards, for its core relevancy.
  • 2. Schema.org: Schema:
  • 3. CDWA: applied as a shared markup vocabulary.
  • 4. CRM: CRM:
  • Regarding the standards, where we could not find the metadata alignement we wrote N/A on the table below.

    Theoretical Model

    The theoretical model displays a new level of interpretation. The model is enriched with information from the Web. The goal is to answer these questions:

    • WHO? People related to the main topic and their role.
    • WHAT? Description of the objects: their scope and features.
    • WHERE? Places and meaningful locations.
    • WHEN? Relevant dates and events.

    Enhanced E/R Model

    From natural language to an Entity/Relationships model again. Similar to the previous E/R model additional information is inserted.

    Conceptual Model

    Finally we reach the deepest level of abstraction through this formal representation. This model is ontological because it represent entities and relationships according to the final adopted standards and classes of the corresponding institutions. The adopted properties are drawn from existant schemas, ontologies and vocabularies.

    Knowledge Representation

       

    Items Description
